[Unlimited Contact Info] Can't save login

I am trying to use “Unlimited Contact Info” plugin to add another communicators. As long as I use it for Facebook or Skype, it works well, but for the Gadu Gadu (polish communicator) it won’t save the login.
After some researches I figured out, that in case there is a space in communicator name (as in “Gadu Gadu”), login value will not be saved. After I deleted “Gadu Gadu” and created “GaduGadu”, it works just fine.

Just in case anybody would have the same problem.

Dear Author, please remove the bug. And thanks for useful plugin!
