[Nightlies]ubuntuone-preferences crashed with ResourceConflict in _request()

[Duane Hinnen]

Clicking System > Preferencces > Ubuntu One while already having a U1 preferences panel open triggered this crash.

To Reproduce:
Click System > Preferences > ubuntu One

optional: lose your preferences window behind your browser so you forget its open.

Click System > Preferences > Ubuntu One (while the first instance is still open)

What I expected to happen. One of three things:
For the first instance to quit.
For a second preferences window to open, so i would have two U1 preferences windows.
Nothing. Trying to open a Ubuntu One preferences while its already open does nothing (maybe bring the application into focus)

Launching the second preferences window in the Terminal:
duanedesign@duanedesign-laptop:~$ ubuntuone-preferences

I just tested this with 1.3+r523-0ubuntu1~ppa1~lucid and it worked as expected: the existing Ubuntu One Preferences window came to the front and no crash occurred. I tested this opening the second instance from both the terminal and from the menu.

Duane, if you're still seeing this issue, let me know. For now I'm marking as "Fix Released".

Thanks,

Joshua
