Bug#643309: gnome-terminal: occasional segfaults when used with xpra

Package: gnome-terminal
Version: 2.30.2-1
Severity: minor

Since I've started using xpra (backported from unstable/upstream svn)
gnome-terminal has segfaulted occasionally (maybe once a month). The
core files are 18 MB and probably have sensitive information in
backlog. This is also a xen dom0 in case it matters. I'm sorry for not
being able to provide more information at this time, I just thought it
would be a good idea to get this information out so that others can
google for it.
