I also have the same problem, GTA04A4. I don't have a FR around anymore,
because the charging is broken.

I'd would also like to have a look at this, could you point us on how to
enable logs? (I played a bit with the logging* scripts, but I have not
been able to get any output from QtMoko - only system log. It says
something about selecting the QtMoko log catrgories - but I have not yet
found out how to do this.

I can't promise I actually can fix anything (never before programmed in
Qt/QtMoko), but I definitively want to give it a try.
