--- Comment #7 from Roland Vet vet.roland@gmail.com --- I think you are right about it happening after a crash, not being the cause of the crash. That log was the game freezing, but it wasn't 'recognized' as a crash, so no minidump was made. When I exit the game manually (killall SC2_x64.exe, the game sometimes freezes on pressing 'Exit'), the same messages were in the log.
I haven't extensively compared the terminal outputs between working and non working but I believe they were similar, if not the same.
I've attached the entire crash log in a zip, and the minidmp again seperately.
