Qt Visual Studio Tools. An item with the same key has already been added.

Something happens with Qt Visual Studio Tools extension (version 2.5.1).
For example, when I try to "Open Qt Project File (.pro) ..." via extension menu, it shows message box with the message "An item with the same key has already been added."
I tried to re-install it, but it does not help.
How to fix that?
