Version: 1.28-19
Severity: important
Recently I enabled selinux on my desktop box and ran into a bad bug in
wdm (Maybe this bug is not in wdm than in glibc, so feel free to
reassign)
WDM starts without any problem but when I log in as user, it crashes
with the following stacktrace:
: Failed to get default security context for klaus.
wdm: *** Error in `-:0 ': free(): invalid pointer: 0x80101d24 ***

(The trace is from a i386 box but the bug also happens on a amd64 one)
I was able to reporduce that bug on a second machine. It is not possible
to log in with selinux enabled (even not in permissive mode as I have it
currently:
~> getenforce
Permissive
As told above, that might be a bug in glibc. In this case, please
reassign.
Not related to the box I run reportbug as the one I tested selinux has
normal debian kernel and the one I run reportbug has a custom one
without selinux.
