Description of problem:
With abrt-2.14.4-6.fc33 from https://bodhi.fedoraproject.org/updates/FEDORA-2020-7cad807210 , when I try to report a crash and send it to the retrace server, it says "preparing environment for backtrace generation" and then the whole libreport window disappears. In journal, I see:

How reproducible:
tried twice, happened twice

Steps to Reproduce:
1. will_abort
2. click Report in ABRT
3. confirm sending to retrace server
4. see the window disappear after ~10 seconds

Additional info:
I'm not sure whether this is a libreport crash or an abrt crash, because the crash itself references report-gtk, but the journal also says "abrt-applet[3947]: free(): double free detected in tcache 2".

Comment 2 Kamil Páral 2020-09-24 10:44:24 UTC 
Proposing as a Beta blocker, this is another episode in the "What the hell happened to ABRT in F33?" documentary. However, note that bug 1881745 seems to be fixed now, so local generation can be used, if you reject remote retracing first. For that reason, this might be deemed to be a Final blocker instead, so proposing as a Final blocker and Beta FE as well.
Comment 3 Matej Grabovsky 2020-09-24 12:15:12 UTC 
Do you think you could upload the coredump as well?

coredump

Here's the coredump. If this is not helpful, I can try to gather useful information from it using gdb. I'm just juggling a bit too many things at once right now :-) Let me know, thanks.
Comment 5 Kamil Páral 2020-09-24 12:56:08 UTC 
Btw, this should be trivially reproducible from a VM with F33 Workstation Beta 1.3 installed and the latest abrt bodhi update applied:

Comment 10 Kamil Páral 2020-10-01 08:57:05 UTC 
With
abrt-2.14.4-6.fc33.x86_64
libreport-2.14.0-11.fc33.x86_64
this problem seems to be resolved. The libreport window crash no longer happens. That doesn't mean that the retrace server works, it simply returns "Retrace job failed". But at least libreport is no longer crashing.

I think we can close this once libreport-2.14.0-11.fc33.x86_64 hits stable repos.

Can you report another bug for this? That should be a final blocker IMO (basic functionality failure). If we cannot fix the retrace server ASAP, then ABRT needs to stop attempting to upload core dumps to the retrace server so we stop failing by default.
Comment 12 Miroslav Suchý 2020-10-02 07:38:01 UTC 
FYI @mgrabovsk is investigating while the retracing always fails. He should have some news soon.
Comment 13 Ben Cotton 2020-10-02 17:12:08 UTC 
FEDORA-2020-6fc633096b was unpushed, so I'm setting this back to ASSIGNED
Comment 14 Ben Cotton 2020-10-02 17:14:52 UTC 
Actually, it looks like FEDORA-2020-6fc633096b isn't the update that includes the fix. FEDORA-2020-e3af715292 does and it has gone stable so I'm closing it per Kamil's comment #10.
