#1 Crash in A3 when using GUI

[zth]

Crash in ardour3 when using GUI. Happens on various occasions (browsing for files/closing the GUI etc), but not all of the time. Not confirmed if this is indeed a Drumkv1-issue, but I figured I'd post it here :). Backtrace attatched.

looks like an issue caused by indirect kde4 native file requester/browser dialogs.

does all crash backtraces look the same or point to same spot (libkio.so.5 and libkfile.so.4) ?

would you try changing the svn trunk source code? file src/drumkv1widget_sample.cpp, lines 525-526, where it reads:

sFilename = QFileDialog::getOpenFileName(parentWidget(),
    sTitle, pConfig->sSampleDir, sFilter);

edit change it to:

sFilename = QFileDialog::getOpenFileName(parentWidget(),
    sTitle, pConfig->sSampleDir, sFilter,
    NULL, QFileDialog::DontUseNativeDialog);

and see if still crashes as often.

cheers

also, make sure you try with svn trunk rev.155+ (aka. drumkv1 v0.3.1.4+)

probably unrelated but there's something that might have killed the suspect message:

lilv_state_new_from_instance(): error: Error saving plugin state: Unsupported flags

Hello!

I did both of those, this time I got a crash when double clicking the sample space to load a sample in my second instance of drumkv1. Attatching backtrace.

Cheers!

it is not clear whether you set the QFileDialog::DontUseNativeDialog option flag. the 2nd. crash backtrace seems to point still to kde4 native file-dialogs and that option flag is precisely to avoid that.

Weird! I was 99% I had recompiled after editing. Anyway, this time I'm certain I have recompiled. Just for the sake of it, this is what I did, stepwise:
1. svn update
2. Edited the file and changed the lines accordingly
3. Saved, exited
4. make
5. sudo make install

Am I missing something?

Cheers!
