Problem w Favourites menu

When I select Favourites, Add from the query window menu, and I enter a favourites name which contains spaces, I almost always get a fatal error message from Windows 7. The image (and text) of the error message is below.
When I restart pgAdmin, the favourite has been added (with spaces.)
If I then try to add another favourite (with spaces in the name,) the same thing happens.
The problem appears to persist until I use the Favourites Manage tool, edit the offending favourite name, and save it. Then, the issue goes away, but ONLY for the current session. If I close and restart pgAdmin, the issue is back again.
Thanks for a great tool - this is the first time I've had a reason to report an issue, and I've been using the tool since pg version 7.3
