Thank you for the bug report! Unfortunately I can't reproduce it myself and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #4  0x00007f49743eefae in  () at /usr/lib/x86_64-linux-gnu/qt5/plugins/discover/flatpak-backend.so
> #5  0x00007f49743ff76b in  () at /usr/lib/x86_64-linux-gnu/qt5/plugins/discover/flatpak-backend.so

Could you please install debug symbols for Discover's Flatpak backend, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
