Yeah, but I build it with yaourt, which likes to contain it's gits elsewhere and apparently deletes them every time as you can't keep a clone unless it's in the same session.
Sounds like a severe yaourt limitation, but maybe you can convince it to clone an existing local repository instead of a remote one?
And running glretrace about 10 times on the trace files, no beans on getting another crash.
Then those trace files won't help others reproduce the problem either unfortunately, let alone fix it.
