Bug 509835

Created attachment 185193 [details]
The Exported Failure Log

# SUMMARY

`plasma-drkonqi-6.4.4-1.fc42.x86_64.rpm` failed to generate a trace the first time it attempted to.

# STEPS TO REPRODUCE

1. Induce https://retrace.fedoraproject.org/faf/reports/bthash/30d842ce033b5a7db20734fd2361e4ec959273dd of https://bugzilla.redhat.com/show_bug.cgi?id=2271266#c22, per https://bugs.kde.org/show_bug.cgi?id=509834#c0.

2. Generate a backtrace.

3. When it fails, "Reload" it.

# OBSERVED RESULT

First, it fails:

Afterward, it succeeds.

# EXPECTED RESULT

It should always generate a trace.

# ADDITIONAL INFORMATION

- This appears most similar to the error logs in https://bugs.kde.org/show_bug.cgi?id=507143#c0:~:text=return-,INTERNAL_SYSCALL_ERROR_P,-(ret)%20?%20INTERNAL_SYSCALL_ERRNO, except that what https://bugs.kde.org/show_bug.cgi?id=507143#c1 describes cannot have occurred.

- Considering that https://github.com/abrt/gnome-abrt/issues/392#issue-3446024444 also occurred, this might relate to it.
