Blah, sorry, I lived in a theory, that Rafael got one from 2.6.25 and no, really, he had -git2 applied. Mea culpa, anyway I'll test 2.6.25 too, just for sure. > Also, it does seem like you can re-create this at will in ways that others > can not. Could you try to bisect it a bit?

Not really. I have no idea what triggers it. Seems like suspend is some kind of catalyzer not working every time. I can't get it to crash for 1 whole day. Probably with the program (I hacked it a hour ago or so) it would be easier to reveal the error far before the crash itself. Will keep you informed. Now going to catch some sleep.
