--- Comment #1 from Ciaran Gillespie <ciaran.gillespie at gmail.com> ---
I have a similar problem with that function as well. Not sure if it's related,
it on a SPARC64 system running Debian Wheezy with Konsole 4.8.4 as well. This
is the back trace from the system.

Program received signal SIGBUS, Bus error.
