(In reply to comment #25)

> Are you able to reproduce this?

Not a will or in a totally predictable manner.

> Any good backtrace for this?

I never observed abrt catching that. OTOH these are recent log entries
(updated Fedora 13 installation, nspluginwrapper-1.3.0-13.fc13):

Due to a bug 658225, which made flash with npviewer totally unusable, I had to bypass nspluginwrapper with flashplayer after installing a 64-bit beta version and that stopped these. December 10th is a date I updated to firefox-3.6.13-1.fc13 and xulrunner-1.9.2.13-1.fc13 with a resulting collateral damage. Still whatever evil things flashplayer is doing does not seem to be a good enough reason to segfault npviewer.bin (only right now that really does not work, period).

OTOH just today I got SIGSEGV in /usr/lib64/xulrunner-1.9.2/plugin-container but from a backtrace this may be rather related to a bug 663507.

Still on CentOS 5 with nspluginwrapper-1.3.0-9.el5 I am collecting quite regularly:

I do not have a good recipe to reproduce that either but it appears that any plugin activity sooner or later will end up with one of these.
