#151 Unavailable mounts cause beachballing, prevent File>Open etc
On Mac 10.4.11 (both intel and ppc), SV 1.7.2, I have problems opening a file chooser (for example to open a new audio file or to Save-as a project), because choosing the menu option starts off something that tries to access network shares which may or may not be available (they certainly aren't mounted, and I don't think they're even in SV's recent files list). This causes beachballing (frozen GUI) for many minutes, before an error dialog appears and I can't proceed.
(I am able to open files by drag-and-drop.)
crash log from 1.7.2a on 10.4.11intel mac
On my own laptop I have an old alias (not a symlink, a mac-style alias) on my desktop which points at an old server no longer existing. I hit this bug again, so I trashed the alias and restarted SV, and now I can open a file dialog fine.
It's possible that the issue could be worked around by setting QFileDialog::setResolveSymlinks(false) on the Mac build. (I can't compile sv on mac so I can't test this!) It would be a shame since I'm sure it's nice usability to have symlinks work transparently.
OK just tried on the hg version of SV, and QFileDialog::setResolveSymlinks(false) DOESN'T fix it.
I found q QTBUG entry that seems to match, suggesting we may need to wait for qt to get fixed:
http://bugreports.qt.nokia.com/browse/QTBUG-6039
In case useful, here's a backtrace captured just after pressing Cmd-O and getting SV beachballing.
