I'm thinking this crash came from http://weblogs.mozillazine.org/asa/archives/2008/11/munch.html which has a flash video, HTML5 video and the plugin checker on it.

npdeploytk.dll has to do with java.  I'm thinking the plugin checker on Asa's page caused this crash but I can't reproduce it.

Reproducible for me.

I have gotten the same stack trace several times:

I've got some seriously freaking UI changes when these bugs happened.

Once, the crash ID appeared to the right side of the browser. In other case, I got a strage "(Something) Script" button to the left side of the browser. 
These UI changes looked like "panels".

I cannot explain this UI behavior. I'm not sure if its an extension. If it happens in a clean profile, I'll post it here.

I would say this bug is completely reproducible.

In this crash thread, I can see some code imported from the Chromium project and a mention to a plugins module: I'm supposing this is caused by the mozilla-runtime process.

BTW: It happened to me while I had Plugin Checker opened... That corresponds to Kurt's thoughts.

The UI behavior is a different (known) bug. Please leave this bug about the crash when java is instantiated.
