I figured out how to reproduce the crash on my system if I have more than 15 updates selected at once it will crash. so i can update the whole list of pacakages by selecting 15 at a time, however they don't seem to be achtually installing and the updates will just come back when i check for updates
This is super weird. I can't reproduce and the backtrace doesn't really bring any information. Maybe you could bring the rest of the threads?
Created attachment 130980 [details] gdb output here is a new log I got with GDB (was using drkonki before) I'm not too familiar with how to debug kde applications so, I apologize in advance if I make a mistake

Created attachment 130985 [details] gdb log with crash I was able to get it to crash by searching and browsing for new themes and stuff while updates where running in discover
Created attachment 130986 [details] gdb log with crash was able to produce a crash by searching/borowsing for new addons while updates are runing
Should be fixed by a combination of the fixes from Bug 427201 and Bug 426732!
(In reply to Nate Graham from comment #12) > Should be fixed by a combination of the fixes from Bug 427201 and Bug 426732! The bug is still there: Discover notified me of the presence of updates for add-ons, I tried to install them but it crashed. It is reproducible every time. Please see attached backtrace.

It is currently fixed for me.
Let's close as fixed, there's been a lot of fixes since that date and the reporters cannot reproduce anymore. Please reopen if you get it to crash on a supported release.
