Description of problem:
On Fedora 34, ABRT does not catch a simulated segfault. A couple of days back, it seemed to work normally, however I did not test a simulated segfault.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install the will-crash package.
2. Issue the will-segfault command.
3. Wait if Abrt reports the error.
Abrt will not report any error, nor show them in the list of errors.
Abrt should be able to catch the error and list it.
The sleep trick also does not make ABRT to catch it:
1. sleep 1000 &
2. kill -s SIGSEGV %1
In journalctl, the crash is visible:

There are also some abrt lines, since the boot, but do not know whether it has anything to do it with the problem:

Tested also in a VM with freshly installed Fedora 34 Beta RC -> same result.
Proposed as a Blocker for 34-final by Fedora user lruzicka using the blocker tracking app because:
I am proposing this as a final blocker for Fedora 34, because this problem violates at least two release criteria:
* SElinux and crash notifications -> non working abrt cannot ensure this.
* Default application functionality
With setenforce 0, Abrt is able to catch it. I will look into the SELinux messages more later.

This looks fishy.
I just tried this on my F34 laptop, and had no problem. I ran will_segfault and a notification showed up right away.
I do not have a ~/.abrt at all. Nor do I have a ~/.cache/abrt/spool ; ~/.cache/abrt exists but contains only the file applet_dirlist .
That error looks like it comes from abrt's `migrate_to_xdg_dirs`. Still, unless I'm missing something, it doesn't look like it's fatal.
Discussed during the 2021-03-15 blocker review meeting: 
The decision to delay the classification of this as a blocker bug was made as this isn't a completely clear call for Final blocker, so since it's confirmed fixed in Beta anyway we're just going to duck it by waiting for that fix to be pushed stable.

The decision to delay the classification of this as a blocker bug was made as this looks like a potential blocker, but we'd like to gather more data and have other testers confirm before deciding.
I'm not able to reproduce on F34 KDE Beta with all updates applied.
I have the same error on Fedora 33.
"systemctl --failed" always shows at least abrt-xorg.service
digging into the journal using "journalctl -xe | grep abrt", I get the following error:
Mar 23 12:08:24 localhost.localdomain abrt-applet: Failed to rename ‘/home/ramizouari/.abrt/spool’ to ‘/home/ramizouari/.cache/abrt/spool’: No such file or directory
ABRT works for me on fully updated F34 machine.

Is this clean installation, or upgrade from F33? In my case, it was a clean installation. It is possible that there is some upgrade bug.
Did you figure anything out yet, Lukas?
Discussed during the 2021-03-29 blocker review meeting: 
The decision to classify this bug as a "RejectedBlocker (Final)" was made as this appears to be a corner case affecting upgrades only, most testers cannot reproduce it, so impact does not seem broad enough to qualify as a blocker.
Hi Lukas. Do you remember if this was a clean installation or an upgrade from older release?
Hi Michal, mine was definitely an upgrade from F33.
Thanks for the confirmation. This looks like it could be related to https://bugzilla.redhat.com/show_bug.cgi?id=1881984
