Firefox crashes upon closing add-ons window

[leet_linux_user]

Binary package hint: firefox-3.5

Each time I open Tools->Add-ons in Firefox from the menu, and then I close the Add-ons window, Firefox crashes. I have ran firefox -safe-mode in a terminal, and checked all of the settings to see if any of those were causing the problem, and they were not, because Firefox still crashed. I ran Firefox in gdb and received the following output.

This has not been happening anymore. Possibly there was a memory leak and rebooting fixed it.
