As I released the newest version 1.4, I have to admit that I didn't test it on Android 1.5. I also missed an API call I made on a method that is available since API level 4 only... This is what caused the FC on Android 1.5 (mostly HTC Hero from what I know), whatever SABcontrol version you had (free, donate or plus).
I have corrected this bad issue I introduced and of course tested the fix on the 1.5 emulator before I released it ;)
Sorry for the inconvenience
