You seem to be using a self-compiled Qt, and it seems to have been built without session management support. Could that be your problem?

Nice to hear it helped!

Btw, note that there are daily builds available for Ubuntu at the [mapeditor.org PPA](https://launchpad.net/~mapeditor.org/+archive/ubuntu/tiled). Install the `tiled-daily` package if you just want the latest version.
