Cannot change owner of Product

[Samuel Schluep]

Hello

As owner (schluep) of the Launchpad product pages "Silva dLCMS" I wanted 
to change ownership to the according development team 
(dlcms-developers). After entering the new owner in the change 
maintainer form a message "Not allowed here - Sorry, you don't have 
permission to access this page" is presented.

It is true that I do have another account (schluep-ethz) with the same 
full name (Samuel Schluep) as the owner account. Using this login 
Launchpad will not allow me to go to the change maintainer form. This is 
what I expect.

I have already successfully changed the products owner earlier (about 5 
months ago). What happened?

Best regards
Samuel
