Description of problem:
When I close a tab containing an IBM server remote management applet, firefox segfaults.
This may be specific to the particular applet as I tested some tests applets at sun.com and FF did survive..but anyway, it shouldn't crash.
Core file is attached.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. login into the IBM remote server web tool
2. use their applet
3. close the tab with the applet
did not happen in F10, so I suspect it's actually a regression in Firefox.

rv = mOwner->GetDocument(getter_AddRefs(document));
so i suppose the mOwner is null or some bogus value. Matej, can you attach the mOwner value and some extended bactrace with local variables?
That's better answered by Jakub ... I have never seen that IBM Java thing in my life.
The mOwner value indeed is NULL:
805 rv = mOwner->GetDocument(getter_AddRefs(document));
(gdb) print mOwner
$1 = (class nsIPluginInstanceOwner *) 0x0
We filed this bug in the upstream database (https://bugzilla.mozilla.org/show_bug.cgi?id=499295) and believe that it is more appropriate to let it be resolved upstream.
We will continue to track the issue in the centralized upstream bug tracker, and will review any bug fixes that become available for consideration in future updates.
Thank you for the bug report.
