I have ubuntu 13.04 installed and am using firefox. I'm confused why i can't launch transmission as the app of choice. It worked fine on my previous installs. I couldnt find any information on the subject and this is my first time encountering it. I've already reinstalled both firefox and transmission to no avail. When hitting get magnet a box pops up prompting me to choose application. Normally transmission would be listed here. By searching for the application i can't find it. It doesn't show any applications to choose just files.
