Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong: #6 0x00007f04d44decd2 in () at /usr/lib64/qt5/plugins/discover/flatpak-backend.so #7 0x00007f04d44def39 in () at /usr/lib64/qt5/plugins/discover/flatpak-backend.so Could you please install debug symbols for Discover's Flatpak backend package, 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!
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
Hey Nate, Sorry for not responding earlier, somehow the e-mails for this but report got sent to a different tag in my GMail. I often update through CLI and seldom through Discover, but I will try to replicate the bug as soon as I get a flatpak update. Thanks for looking into it.
Nate, I tried twice this week and I can't replicate it anymore. I will close the bug for now, and if I can replicate it I will reopen it again. Thanks!

Adrian, your backtrace looks different so I think it's a different crash. If you can truly reproduce it 100%, please do file a new bug report for it. Thanks!

I've tired to use the "Report Bug" button on the "Discover -- The KDE Crash Handler" window, but it keeps telling me "This report does not contain enough information for the developers, so the automated bug reporting process is not enabled for this crash". I select 'Yes'/'Every time'/'What I was doing when the application "Discover" crashed' options of "What do you know about the crash?".
That probably means you don't have debug symbols installed.
(In reply to Nate Graham from comment #8) > That probably means you don't have debug symbols installed. That stack trace isn't enough? Seems like an uphill fight just to do the right thing and report a bug. :/
Indeed, unfortunately some distros don't make it easy. I wish they all did. No, the stack trace is not enough if it's missing debug symbols. That makes it impossible to debug, except for *maybe* identifying the issue as a duplicate of another one.

I am wondering if maybe we are simply closing resources out from under the flatpak worker thread.
Is anyone able to reproduce this on 6.x?
