Solved: Braid segfault
Downloaded the Braid game from the latest Humble Bundle V. When I start the game on my Debian testing system, immediate segfault. Well, this may fix it for ya!
See if you have the following two libraries installed on your system. In my case, they were already in /lib/i386-linux-gnu and /usr/lib/gcc/i486-linux-gnu/4.6/
so I disabled the versions that came with Braid.
mv libgcc_s.so.1 disabled.libgcc_s.so.1
mv libstdc++.so.6 disabled.libstdc++.so.6
Voila! Braid now runs.
