npviewer.bin[21826]: segfault at 80000000 ip 0000000080000000 sp 00000000ffca01fc error 14

I see that too often as well.

Comment 2 udo 2010-02-24 16:36:05 UTC

It happens when the vids are *idle*.
It wastes CPU.
So it wastes electricty.
So this bug is bad for the environment, assuming that most of the electricity is generated in a non-green way.
PLEASE fix.

Need more info?

Feel free to write the patch and I'll happily test it. The current state of this bug is that I have no idea how to fix it unless we want to break some plug-ins.
