double entries in widget list

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hi all, 

does someone know, how I can get rid of the double entries in widget list in 
kde4? I downloaded some google widgets twice, and now there are double entries 
in the widget window (the one, which pops up, and where I can choose the 
widgets). Is there a file, where I can edit it?

Thanks for any answer.

Best greetings

Hans
