Bug 440185

When changing the name of a track, I expect that pressing RETURN will finalize the editing. It even looks like that, the cursor dissapears - but it doesnt. Pressing another key - like a shortcut - does not work, and clicking outside the name widget will show that that character (or characters) were added to the name. This behavior is different from other similar actions, like renaming tracks or ediging track descriptions, both of which functions normal - RETURN will finalize editing. 

STEPS TO REPRODUCE
1. doubleclick in the track name area (hey, why not F2 here??)
2. Type a nice track name, press RETURN to finalize
3. type another character, like a shotcut for something

OBSERVED RESULT
The last character typed in step 3 above has no effect. There is no visual indication of why not, until you click somewhere outside the track name area, and realize that the last character was secretly added to the track name.

EXPECTED RESULT
RETURN finalizes the editing og the track name, and focus is back on track.
