Severity: important

Hi,

due to a bug in ext4 my archive for locales
(/usr/lib/locale/locale-archive) became corrupted. This caused a segfault
in all programs they tried to do something with locales.

That's the top of the backtrace of a crashed program

Unfortunately, I've didn't saved the locale archive before rebuilding it.
I hope you get enough informations from the backtrace to find the bug.

If the archive becomes corrupted, the whole system is unusable, I can't
login nor do many services not start.

Bye, Jörg
