Description Aaron Williams 2020-01-25 19:50:53 UTC
After recent updates to KDE I am unable to start kmail without it crashing. I am seeing other applications crash in the same place, QLocale::toString(QDateTime const&, QLocale::FormatType).

I see this failure in systemsettings5 as well when I click on Regional Settings then click on formats I see a similar crash. Also, the panels at the bottom of my screen keep crashing periodically. This started in the last couple of days.

I am running KDE Applications framework, KDE framework, QT5 and KDE Extra repositories and have verified that everything is up to date in them. I have also verified that all of the localization is configured properly (en_US.UTF-8). I forced a re-install of everything as well and it continues to crash.

Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
29	  return SYSCALL_CANCEL (poll, fds, nfds, timeout);

The repos are rebuilding

*** This bug has been marked as a duplicate of bug 1161815 ***
Comment 3 Wolfgang Bauer 2020-01-25 21:02:03 UTC
