When trying to start phlipple, I briefly see a black window, then it
crashes with a segmentation fault. I built it with symbols to get a
meaningful stack backtrace:

My system does not have hardware openGL support, but other 3D programs
work fine (though sometimes slow).

Thanks,

I'm not able to reproduce this bug on either of my two amd64 machines
with hardware acceleration (intel, nouveau drivers). When I set the
LIBGL_ALWAYS_INDIRECT environment variable, I get a crash though.

On a system with the above CPU and video hardware I get the same GDB backtrace
as listed in this bug report.  I'm running a fairly default configuration of
Unstable.
