System unusable with 100% CPU usage by npviewer.bin

[Ken Hagan]

I've used the "Report a Problem" feature and now find myself here being asked to provide context. Tricky. All *I* know is that for the umpteenth time my son has informed me that the computer has stopped responding and that upon investigation (which sometimes, though not always, involves pushing the big red power button) I find a mis-behaving npviewer.bin process hogging the CPU.

Using gutsy amd64 on a dual-core processor. (On a good day, I get asked to investigate when only 1 CPU has been overrun. On a bad day, it has "attacked" both. :)

npviewer.bin is the non-free flash player.

I can confirm this bug - unfortunately don't know how well this will go because this is a nonfree plugin.

I upgraded to 8.04 several weeks ago and I don't think I've had this problem since.
