Ok, here's a bit more useful info: if I set LANG to C, it all looks pretty 
good.  If I leave one of the fedora defaults, even an english one:

planck[demo]> echo $LANG
en_US.UTF-8

I get guaranteed segfaults.  I'm going to guess it's a bug related to UTF-8 
handling deep in the bowels of wx and/or GTK.

Unfortunately I can't really commit to deeply debugging this problem at the 
library level (WX) right now.  That kind of bug hunting in C libs is very time 
consuming, and at the moment I can only spend short bursts of time on this 
performing small tests.  Hopefully the LANG info  proves useful, since that's 
the most I'm likely to be able to provide.  Can you see if you get similar 
problems with UTF-8 settings?

Perhaps doing a hard LANG=C inside gui_thread is a viable option also.  Not 
ideal, but better than a segfault :)

Cheers,
