On the page where I'm asked for a root password twice, when I click the entry dialog, it swallows my first character. I have never seen a program do that, and it took me three runs to realize that I wasn't typing it wrong all the time. One of the most amusing bugs I've ever run into :)

There is no method clicked to the GtkEntry widget so I'm not sure how to detect the initial change being made other then to wait for the first key press ... :/
