Description robert fairbrother 2021-02-19 08:14:36 UTC

the previous version of fedora 34 stopped updating and i could not run the kernel regression tests with the -performance option so i have just upgraded to fedora 34 again
after reinstalling it on this acer Aspire 4720 laptop.
when i installed fedora 34 i reboted and logged in, shortly after that i knoticed applications would close soon after being opened, i may have tryed to do killall -w -ABRT -u, i have no w ran updates with dnf in the comandline and rebooted to find these error reports have now appeared inder the abrt-cli program (they werent before)

Am I understanding correctly that you typed this:

    killall -w -ABRT -u

In this case, you just sent `SIGABRT` to all processes of this user, thus including the dbus-broker processes running under this user. So this bug-report just states that dbus-broker exited due to `SIGABRT`, which is exactly what you wanted it to do?

`SIGABRT` is not used by any dbus-broker infrastructure, so the coredump you posted indicates the signal was sent from another processes. In this case, you really need to report this bug to whatever sent this signal. If you did not sent it yourself, and you have problems identifying which process sent the signal, we can try to work this out together.

yes i used killall -w -ABRT -u
my entire uses session was unusable  so i didnt kn ow where to send it 
im thinking it might help to login to my account and then run startx with the &> option to append the terminal output to a text file and upload that to someone?

what really gets me is that more often thain not now when something is broken and my computer becomes unusable abrt dosent detectc any problem or the problems it detects are not reportable for some reason or another like incomplete problem data

This is quite unfortunate. Though `killall -w ABRT` just causes all your session processes to dump core, and thus trigger `abrt` to send those as bug-reports. However, in this case those processes were not necessarily involved in whatever problems you experienced.

If you have particular issues, I recommend filing these as individual bug-reports with a full description of the issue. Unfortunately, the core-dump you provided in this report is not suitable to debug anything but the message broker on your system (which in this case did not behave abnormally, iiuc).
