I cannot reproduce the issue although I'm using Ubuntu 10.10 x64 as well.
What do you mean exactly by "The GUI hangs"? Is it unresponsive when you try to do something? Is CPU usage abnormally high when this happens? How about disk activity?
Are you saving to a unusual location? for example, an encrypted drive or folder, A network drive, a Non-Linux file system (e.g. NTFS). There are to be something different with your configuration or I would get way more bug reports about this.
