I can't even get it to run with apitrace (tried even with git master):

apitrace: redirecting dlopen("libGL.so.1", 0x102)
nv50_screen_get_param:181 - unknown PIPE_CAP 76
apitrace: warning: caught signal 11
apitrace: ignoring exception while tracing

For some reason i can't catch it with gdb, the process always exits
and then i cannot get a backtrace.
