@qwerty12 That did it!

Dexter can now be found from Extras-devel. Now that the hurdles to get this application there are done, I'll work on getting a more stable version there.

@Opa: Something you might try and report: Launch Dexter from xterm and see the output. It might tell something about the reasons the app is crashing. You can do it by running this: "run-standalone.sh /usr/bin/Dexter"
