I'm not quite sure. My best guess is that this has to do with the inconsistant naming of the dbus service within tear itself (com.nokia.tear vs. com.nokia.Tear). However, it could also be due to my OS. I have my OS cloned to SD card, I've fsck'd it a couple times, and it has deleted some files it probably shouldn't have. I also seem to have dbus problems with some other applications, so that might be the cause of my problems.
