FWIW I'm running Discover built from source in KDE Neon dev unstable and I don't see this crash.
Thread 12 is the one that crashed? Was this generated from konqi?
(In reply to Nate Graham from comment #2) > Thread 12 is the one that crashed? Yes. (In reply to Nate Graham from comment #2) > Was this generated from konqi? No. drkonqi is useless on neon dev unstable because it never installs debug packages to generate good backtraces.
Can you reproduce? How did you get the crash?
Crash notification immediately appears when I click Discover icon from apps menu.
Can you still reproduce it? 388730 suggests it got fixed.
The backtrace (thread 1) is nearly identical; I think we can mark this as a dupe of 388730.
(In reply to Aleix Pol from comment #6) > Can you still reproduce it? No. Thank you all.
