Matt - are there any more details I can send that will help pin down the problem? I tried running the game with strace but nothing jumped as being a possible culprit.
Dan was able to reproduce it on his OpenSUSE machine, so it should be fixed for the next build! Thanks for trying out the Linux build. I always worry about our linux build just because there are so many distros out there... I'm glad at least one person is beta testing on Linux.
