SUMMARY
I am trying to align multiple video/audio clips with one longer audio clip and
it always ends with segfault.
STEPS TO REPRODUCE
1. timeline: 1 video track, 2 audio tracks
2. add one long audio clip (drag and drop from project bin)
3. add several shorter video clips with their own audio (multiple select by
mouse with shift from project bin and drag and drop to timeline)
4. right click on long audio clip and choose "set audio reference", wait till
the reference is set
5. with mouse and shift choose shorter clips in timeline
6. right click and choose "align audio to reference"
OBSERVED RESULT
segfault
I tried to catch some backtrace with gdb, but I am running Kdenlive from
appimage, so I don't know if the backtrace will be useful.
Thread 866 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

EXPECTED RESULT
Clips should be aligned to reference audio (or at least some error should
appear that clips cannot be moved or something else, but there is a lot of
space on both sides)
SOFTWARE/OS VERSIONS
Linux: Debian 12.7, kernel 6.9.10+bpo-amd64, Gnome 43.9
Kdenlive appimage: kdenlive-24.08.1-x86_64.AppImage
ADDITIONAL INFORMATION
I have tried the same alignment with several Kdenlive older versions up to
kdenlive-23.08.4-x86_64-A.AppImage and all end with segfault.
