User zimlet functionality broken

[robtain]

I enabled some zimlets in zimlets-extra that I thought would be useful to our users.
After testing each one in turn, I added preview, survey and support tool to tray them out, not it appears that zimlet functionality is broken.

I undeployed and disabled most of the zimlets that I added, but they still appear in the list. In the zimlets sidebar, zimlet names appear as garbage:

Is there anyway I can easily reset my zimlet config without screwing up the LDAP?

Thx
