Description of problem:
Suppose user added 2 languages and those are showing in the language pane. Now, if user delete/remove one selected language, after deletion, the focus aotomatically shifted the one remaining language. But, its a dummy focus, and as result, user can see that the Remove button remains disable and the desciption of Alias fonts for that language is also now showing. In this case, user needs to press CRTL and select that language (which will actually work as deselect) and then again select it fresh, then all the disabled fields will be enabled. Its a confusing factor for any user. It should be rectified.

Version-Release number of selected component (if applicable):
fonts-tweak-tool-0.0.5-1.fc17.noarch

How reproducible:
Always

Steps to Reproduce:
1. Open fonts-tweak-tool
2. Add 2 languages.
3. Now, delete/remove either of the two.
4. Observe the focus shifted on one remaining language, but also observe the "remove" button become disabled, and the Font alias section, showing nothing.
  
Actual results:
Focus shifting is acting as a dummy focus.

Expected results:
Focus should not be dummy and the expected scenario should be met.
