Still crashes, even after restart X (for the 3rd backtrace here only),
but different traces:

Ah, so that's planned for 7.10-5 or so ? But then 7.10-2 would have
made things better, if I understand well.
I also note that I still have the old 7.7.1 glu packages. Not being
sure about the effect of any mismatch here...
Should I try to downgrade any other packages ? Or to another specific
version ?
