npviewer.bin segfaulting

[Patrick O'Callaghan]

I'm getting frequent segfaults which crash Firefox:

etc. etc. etc.

They start on Oct 12, which coincides with the last update I did (a
groupupdate of KDE from updates-testing-newkey). This is F9 on a x86_64.
I can't do far pin the segfault down to a specific page or media type. I
did a "mozilla-plugin-config -i" a couple of hours back and it hasn't
happened since, but I thought I'd mention it in case anyone else had
seen this.

I'll post a followup if it happens again.
