SUMMARY

Discover crashes when opening an app details page of an app that is available from a local source, for example because one used flatpak-builder --install.
Since the crash references the IconUrlRole, discover might crash on every repository that doesn't have an icon, but I wasn't able to verify that.

gdb output of the crash:
Thread 1 "plasma-discover" received signal SIGSEGV, Segmentation fault.
0x00007fffc42fbb32 in FlatpakResource::sourceIcon (this=0xce8c70) at /home/jbb/kde/src/discover/libdiscover/backends/FlatpakBackend/FlatpakResource.cpp:573
573         const auto iconUrl = qobject_cast<FlatpakBackend*>(backend())->sources()->sourceById(origin())->data(FlatpakSourcesBackend::IconUrlRole).toString();


STEPS TO REPRODUCE
1. Compile an app locally with flatpak-builder --install
2. open the details page of that app in discover
3. See discover crash

OBSERVED RESULT

crash

EXPECTED RESULT

no crash, app details are displayed
