Bug ID: 414862
Summary: ksplashqml crashed after login [double free or
corruption (fasttop)]
Product: plasmashell
Version: 5.17.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: szots...@gmail.com
Target Milestone: 1.0
SUMMARY
After a logout I logged in again when DrKonqi reported that ksplashqml has
crashed.
Additionally, it's not possible to report ksplashqml crashes via DrKonqi since
the "Report error" button is disabled there.
Backtrace:
Application: ksplashqml (ksplashqml), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
29 return SYSCALL_CANCEL (poll, fds, nfds, timeout);
