I attempted to compile and run the SVN snapshot and after a bit it crashed, I don't know why and when I went for the backtrace it said it was either disabled or the stack was corrupted exceptionally badly, as I'm guessing it was the prior, how would I go about getting the debug information or the backtrace?

If you run it in the shell, do you get any output on the shell?

Apparently it was just badly corrupted because without any changes the next backtraces I got worked fine, running it in debug mode Qt complained about not being able to discard an object it was currently painting though.
