At very least I need a backtrace or a way to reproduce this. I have been trying Discover on Fedora, haven't been able to see this (or any) crash.
Created attachment 115579 [details] Discover gdb output
I made a new attachenment with GDB output, and I've upload a video of reporcedure which available here: https://www.youtube.com/watch?v=hpv_r_A4j88 Regards
Hi, You almost got there, can you type "where" to get the full backtrace? Let's hope we can find where the problem is! By the way, you are hitting a bug I already detected (only happens in fedora, fixed it a couple of days ago)
(In reply to Aleix Pol from comment #4) > Hi, > You almost got there, can you type "where" to get the full backtrace? Sorry this is my fold by long day and long night work that wrong file I uploaded here. If requires in the future I can upload the coredump as well > Let's hope we can find where the problem is! > By the way, you are hitting a bug I already detected (only happens in > fedora, fixed it a couple of days ago) Thanks Alex, this is a very good news, We would like to use the Discover as default package manager. I set this bug as resolved fixed Have a nice day.
Sorry, this crash problem still exists, when the user sufing in menu. I do not found any information or patches on Fedora. Tested versions: Latest Git version and all previous as well.
