Long story short, I didn't want the FM Transmitter status menu applet to hide after I disabled it. Unfortunately, it's closed source and I didn't want to have to add another applet just to enable it. Looking at it, it wasn't complicated so even I could write a clone. It's pretty much a 1:1 clone (with the showing of error messages broadcast by fmtxd over D-BUS, usage of Nokia strings for localisation, and everything). IDA Pro FTW.
Only things I did differently was to ensure that the button is always there in the status area and I made sure that all memory was freed...
