I manually recompiled the upstream source [1] and I got the same
segfault, still without useful debugging information.
Thus, as mixxx is at version 1.5.0.1 upstream, I compiled it on an
updated sid and it still segfault, but with more useful debugging
information:

FWIW, version 1.5.0.1 works with no problem on an updated etch.
FYI, also SVN revision 1171 segfault, but with a different backtrace:

This seems to me related to libGL in sid and nothing changes if I
compile mixxx with the experimental mesa-6.5.3 [2].
Thx, bye,
Gismo / Luca
Footnotes:
[1] not the Debian .orig.tar.gz, which is a DFSG version of the
upstream source
[2] which isn't available yet for amd64, thus I built it on a local
pbuilder
