Hmm, the string "EGL search path is" and the corresponding code was
removed upstream for Mesa 10.6. Look for instances of libEGL.so.1* other
than /usr/lib/x86_64-linux-gnu/libEGL.so.1* on your system and see if
removing those helps.

It's just a workaround. We don't know yet what the problem is, though
it's likely specific to your system.
