I managed to reproduce this in a i386 chroot, and the backtrace looks
pretty much like yours.  It probably looks like that because it's in the
middle of a bunch of varargs functions.

The problem is that in a g_object_new call, the "xalign" property is
being passed an int when it should be a float/double.  x86-64 gets away
with it, I think due to alignment, but i386 gets the types and
parameters mismatched and crashes from trying to treat a TRUE as a
string.

Attached patch fixes it.  Forwarded upstream.
