Digikam 7.2-RC Segfault, no bt

[Gilles Caulier]

Hi,

As I can see you run the AppImage version.

You need to use the heavy debug version of appimage, which include all
debug symbols. Run the bundle in gdb with the debug argument as usual.
Now when it crash you will see a debug backtrace if GDB can capture
this.

Best
