I'm using a N810 with OS version 5.2008.43-7.
I installed APM 0.4.1 and AP 0.3.6 and I just got a red battery icon plus a low battery warning after a few seconds (although the battery was fully loaded) and it was not possible to start APMD from the menu. Then I tried AP 0.3.5 and I just saw an empty slot where the applet icon should be. After installing AP 0.3.4 everything works as expected. No problems so far. I use the original theme and I do not have any other non-Maemo top bar applets running.
Any ideas what prevents my N810 from running AP 0.3.6? Thanks for your help.
