Dear Maintainer, Steps to reproduce: 1. Start GENtle. 2. Open Tools-> Alignment (Or press Ctrl+g). Expected outcome: Dialog with alignment options. Actual outcome: A dialog pops up, but it only contains a Cancel button. (It seems like it contains more controls, but they are obscured by the Cancel button) (This was originally reported in Ubuntu as https://bugs.launchpad.net/ubuntu/+source/gentle/+bug/713273)
