The issue is that the OpenAL we ship raises an exception when it
cannot find the audio device (which may happen for several reasons).
This needs to be trapped by the calling code, to either retry, or
disable audio, or something.
An example patch that I had been using for torcs for the same
issue was as follows:
+diff -urN torcs-1.3.0/src/modules/graphic/ssggraph/grsound.cpp

Applying something similar to the sound initialisation portion of
glest ought prevent the segfault, assuming that glest has some
mechanism to run with sound disabled.
Separately, one can set various options in /etc/openalrc for a
general fallback mechanism to avoid raising this exception, although
the correct configuration for this file depends quite heavily on the
local sound configuration.
