I think you are definetly in the 'something went wild' category.

Looking at the gdb traceback, I'm guessing the stack grew so much that it
grew down into the top of the heap?  

That being the case, it looks like some call to libgail.so is recursively
doing something until it exhausts the stack.  libgail.so looks like a libgtk
interface to the 'gnome accessibility implementation library'.

If you load the libgtk debug symbols for you linux distro, gdb should print
out the symbolic names for the endless loop in the gdb output.
Also, check what version of libgtk you have installed.  The latest
version for version 2 is 2.24.31.

I've had a large folder of mail before, I think it was ~25 to ~30 (70?)
thousand.  I will try creating a ~50k folder and see if I see the same issue. 

Depending on your libgtk version, it might be a known issue, but we probably
need to know the api call from the stack trace to find it.
