Hm, it works for me now without segfaulting... Make sure you have the latest version, 0.2-maemo2. If it it still crashes on launch, I'll need a little feedback: open console and (as user !) type Code: sudo run-standalone.sh /usr/bin/tweakflashver EDIT: Disregard, bratag is right, the settings do not get initialized properly for some reason.
sudo run-standalone.sh /usr/bin/tweakflashver
