Description William Sherwin 2024-01-29 06:58:54 UTC

As an end-user running MuseScore 4.2.1-r1, when either I create a new file or open an existing file and make a change and attempt to save, I get a segmentation fault just after the Save dialog box (pointing to the file system) appears.

Reproducible: Always

Steps to Reproduce:
1. Open MuseScore.
2. Open a file (new or existing).
3. Make a change.
4. Type CTRL+S (or choose File > Save).
5. Select "Save to My Computer".
Actual Results:  
Segmentation fault. With Address Sanitizer configured, the attached traceback is issued when running from a terminal window.

Expected Results:  
The Save File dialog box is displayed, and the User is able to save the file.

Address Sanitizer was configured as per http://wiki.gentoo.org/wiki/AddressSanitizer, and MuseScore was recompiled with it.

Did you have debugging symbols for dev-qt/* (no need for it for qtwebengine) and musescore?

See https://wiki.gentoo.org/wiki/Debugging#Per-package.

I did not: I will recompile and install them.

Are you using Wayland? If so, could you make sure you have dev-qt/qtgui[X] installed and try launching musescore with the QT_QPA_PLATFORM=xcb environment variable?

I am not: I'm still using X11.

With the newer traceback, I actually got the Save File modal; after a few seconds, it vanished with the segfault.
