npviewer.bin crashed with SIGSEGV in pthread_mutex_lock()

[Tarthen Brown]

Binary package hint: nspluginwrapper

I force quit FF when it went grey (stopped responding, rather) after I clicked a Youtube link (which crashed Flash and the browser), and apport came up.

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate an useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

x11-common: installed version 1:7.4+3ubuntu6, latest version: 1:7.4+3ubuntu7

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!
