I got gcjwebplugin 0.3.2-1
mozilla-firefox 1.0.6-3

I was talking about some mechanism to disable this specific plugin
(gcjwebplugin) in firefox, or some trick to do this by editing
configuration files, hopefull automatic, but at least an hint in a
README or FAQ file.

mozilla 1.7.10-1 give me the same error

sorry, I thing this is not enought for a bug report, maybe the next
sunday I got more time for this.

Daniele.
