Looks like a threading error somewhere. What version of Tcl/Tk 
are you linking against? Are you using threads in your program? 
Tcl/Tk can be a pain with threading as i've read. There exists 
thread-friendly versions as seen here: 
http://www.tcl.tk/doc/howto/compile.html Notice the 
--enable-threads switch.

I don't really know what to suggest. Try reducing the program 
down until you've found where the issue stops happening. It may 
be an incompatibility with SDL?
