1. Make sure to start Creator without any saved settings.
2. Select "Tools" -> "Git" -> "Remote Repository" -> "Gerrit..." from the menu.
   The Options dialog will open.
3. Click "OK" without entering anything.
   The dialog will close and come back right away. There's no kind of information that this happens because no User or Repository have been entered.

If data is missing, Creator should inform the user what is missing. This could happen in step 2 already. Without such an information, this situation looks like an endless loop.
