 I've been caught out by this several times - usually when I've got a bunch
 of unsaved changes :(

 I've managed to get a reliable (for me) set of steps to reproduce, even if
 it's not a minimal test case:
 1. Load potlatch.
 2. Draw a new closed way.
 3. From the presets menu, select "Transport" section, and "Car Parking".
 4. Click 'Advanced' at bottom. Then 'Add' for a key
 5. Type 'access', <tab> 'perm', select "permissive" from auto-complete
 menu.
 6. Press 'Add' again, type 'name', <tab> <backspace>
 (at this point, there is a key called 'name' with no value)
 7. Click where it says 'name', (e.g. to try and change to a different key
 such as 'operator')

 Expected result: focus changes to key name, allowing this to be changed.

 Actual result: Potlatch crashes, losing any work done since last save.


 (undoubtedly there are other triggers, as I've stumbled into similar
 potlatch crashes several times, but the above steps did it every time for
 me from a fresh start)
