mount.crypt SIGSEGV's after resume

[Matthias Gehre]

Binary package hint: libpam-mount

After I resumed my thinkpad from suspend2ram, I got a message telling me that mount.crypt has been crashed.
I use pam_mount to mount a LUKS encrypted /home whenever I log in.
After that crash, everything still works as expected.
Please provide me with further directions to debug the problem.
