Activities with accent marks in name

Created by: miguelcordero

If I create a activity with acute mark or accent mark in their name, like "Exposición", hamster doesn't permit save or modify their description. The Save button doesn't work when i type something in description box and window doesn't close. If I type in Title box, after the @, button Save works and closes the window but not saves the new content.

I run Debian 8.2, and i test with hamster_2.0-rc1-2_all.deb and building from source with master release also.
