Unable to add selected web part SharePoint an entry with the same key already exists

description

Hey, thanks for providing this. I installed the solution with no problems but when I try to add the web part I get the error attached. Please see pic and let me know. Did this webpart add the Flash Video content type? If so, I only see two fields. If not, I might have added it earlier. Please let me know if you have any ideas on debugging.
 
Thanks in advance.

BTW, when I click okay it just goes back to the page ;) No errors in the event logs and nothing in the trace logs.

Nice work! Bun unfortunately i do have the same issue as Kosher. Trying to deploy this on a Publishing Site with no luck so far. Anybody solved this issue

I think i have found where this goes wrong, in the .webpart file, there are 2 properties, but both have the same name (Title), it should be Title and Description

P.S. if i add the .webpart file manually through site settings --> webparts --> upload, it works fine???
