exception when all plugins are disabled

removing UserActivity from the *jprefs_comp_off: line in preferences.rdb allows startup of coccinella again.

also got this, after:
setting mood to none
setting activity to none:
disabling the useractivity plugin:

The bug may be related to my code changes to support gettext: http://coccinella.svn.sourceforge.net/viewvc/coccinella/trunk/coccinella/components/Mood.tcl?r1=2602&r2=2649

both exceptions had the same kind of problem, a missing variable in the namespace.
fixed with svn revision #2744 and #2745
