Installed Rosegarden 1.4.0 on KDE3.5.5 "release45" on open SUSE10.2 from RPM. Program opens and runs OK and able to play MIDI files. When I start a new track and open it in the notation editor, I get a freeze on inserting the first note. The "laying out staff..." message stays up. I have to kill the application and restart. I found that if I wait for a while - couple of minutes - I can use the notation editor no problems. If I close it and reopen the section of track it freezes as soon as it opens.

Using kernel 2.6.18.2-34-default

My daughter love this program - great work

    Hello,

    I am also seeing this problem. I tried compiling Rosegarden from source and the problem still occurrs, so it doesn't seem to be a problem specific to the RPM in the Packman repository. I also tried installing the SuSE RPM (from Packman) on Fedora 6 and everything works fine. I have also seen Rosegarden 1.4 running fine on Arch and Sabayon, thus, it appears to be a specific interaction between Rosegarden and SuSE 10.2, or versions of some shared library shipped with SuSE 10.2. SuSE 10.2 uses KDE 3.5.5 and QT 3.3.7.

    Regards,

    Dave

    I found the same problem, which apparently comes from the Feta font. If I change, in Rosegarden settings, the font for Feta pixmaps, there is no more bug.

    Changing the feta font fixes the freeze in the notation editor for me as well. Looking at the font in /opt/kde3/share/apps/rosegarden/fonts/feta/ there are a number of .xpm files with zero bytes. I wonder if this is the cause. Selecting the view button in config rosegarden under the notation options also causes the view window to freeze as well, suggesting that the font is the problem although why it appears to only be a problem in SUSE10.2 I cannot say. I did have rosegarden working under 10.1 straight from the RPM.

    Cheers

    David

    The problem doesn't seem to be in the Rosegarden font dir. I ran Rosegarden on Mepis and Kubuntu, without any problem and replacing OpenSuse 10.2 Rosegarden font dir with Kubuntu Rosegarden font dir doesn't fix the bug.
    But the bug comes surely from that font dir.

    Oops! My previous message is unclear: the bug is in the font dir, of course!

    The xpm files are only used when you set the font to "Feta Pixmaps", not "Feta" (for which an actual font is used). So, the zero-sized xpm files can't be at fault. They've been there for ever, anyway.

    Can you get a back trace while the program is frozen? One way to do this may be to go to a terminal window, type "killall -11 rosegarden" and hope the KDE crash debug window appears. If you can get a trace this (or any other) way, please post it here. They aren't always useful, but they can be.

    I have the same problem on my openSuse 10.2 installation. After changing font to Feta Pixmaps everything works fine.

    I have the same problem here, also on OpenSuse 10.2. Perhaps this is really a Suse bug?

    Well, naively it looks like the Freetype library is having trouble with the version of the Feta font we include.

    Can you try

    kfontview /usr/share/apps/rosegarden/fonts/LilyPond-feta-design20.pfa

    (or /usr/local/share/... or /opt/kde3/share/... or wherever this file has been installed) and see whether the font comes up successfully in kfontview? If it does, please try the same thing with the other two .pfa font files that are in the same directory and see whether any of those causes a hang.

    A more complicated thing worth trying is switching Rosegarden's "feta" mode so that it actually uses a different font. Pick a font that you know displays correctly on your system (doesn't have to be a music font, something like Bitstream Vera is fine). Edit as root /usr/share/apps/rosegarden/fonts/mappings/feta.xml (again, the actual location of this file may vary) and change the name "LilyPond-feta-rosegarden" at line 16 to the name of your chosen font, such as "Bitstream Vera Sans". Make the same change for the font names on the next two lines as well. Then save the file, restart Rosegarden and try opening the font view window in the settings -- you should see your font displayed as if it was a notation font for the Feta option. If that works, it might be worth restoring all but one of the font names in that file to their original values and replacing them one at a time with your known-to-work font, in case it turns out that only one of the three fonts named in there is causing the problem.
