Bug Description

Random crash at Unity session's start.

sudo apport-retrace -g /var/crash/_usr_sbin_unity-greeter.104.crash
... (into gdb)
... thread apply all bt
... bt
... Backtrace stopped: previous frame inner to this frame (corrupt stack?)

The line above is the result into gdb.
Which other information should I collect to help detect how the stack corrupts?
