Yes, that's where I figured the errors are coming from. For now, the way to fix this is to install the old rdesktop frontend and save some settings. However, I've included a fix for the next version. Sorry, I'm still quite new at python, and there's no good reference for python's gconf...

Sparks: Are you running diablo or chinook? If you go to the control panel, and open "About Product", what OS version does it show? My guess is you're running chinook, while this is compiled against the diablo libraries. In the next version, I'll try to include a chinook version, too.
