dvgrab crash __fortify_fail or __GI_raise

[Carl Karsten]

Binary package hint: dvgrab

I am guessing -buffers=1 is a bad idea, but I am also guessing it should be at least handled gracefully.
and, I get crashes when I use the default (-buffers 100) it just takes longer (about an hour.) I don't know if it is the same crash, I haven't yet reproduced it when I had time to study it.

 Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.
