Looks like this is related to broken multi-threading in nouveau, see linked
bugs.

Just run the application in question with LD_LIBRARY_PATH=... (note - using
LIBGL_DRIVERS_PATH is highly unadvisable unless you *really* know what you're
doing. Just build with some prefix, install, and point LD_LIBRARY_PATH at
that.)

Anyways, if doing your own mesa build is beyond your powers that's fine. We can
keep this open and I can assume it'll magically get fixed when I get around to
finishing up those locking patches.
