Windows Presentation Foundation plugin causing crash on exit

The Windows Presentation Foundation plugin that got included in with Firefox/Mozilla over the last year appears to be responsible for KE crashes on exit (at least with my system).

About a week ago Firefox 3.5 disabled the plugin (I got a notification that it was being disabled and needed to restart Firefox), reporting it as a security risk. It also appears to be responsible for Firefox crashes reported by a lot of users.

The plugin is still included in the Mozilla framework in the latest KE 5.2. I've disabled it and KE stopped crashing on exit.

Thought reporting this here might save you guys some time.

I've added a bug to look into this problem:

Are you 100% sure this plugin was the cause of the Komodo crash on exit?

Yes

Yes. I don't know when the Mozilla part of KE was updated and the WPF plugin added in, but as soon as I disabled the plugin, the crashes on exit stopped.

It's also possible that Firefox has added something to their code to block the WPF plugin (because as the links I posted show, it's a security risk), and the presence of the plugin in KE still sets this off. Which would still mean the plugin is responsible.

I'm not totally sure that's possible, since they are different applications, but I'm sure that once the plugin was disabled in KE, the crashes stopped.
