[i'm forwarding this debian bug report (http://bugs.debian.org/656443)
to the upstream development list as well]

I can replicate this on an i386 build as well.

When i do ctrl-shift-E, i get the following backtrace:

Program received signal SIGSEGV, Segmentation fault.

and from the menu:

Any pointers on what to look at to get this fixed?
