Well there is a line "rfkill block bluetooth &" in qpe.sh, so I guess
that is what blocked it.

Also I'd guess now that this problem - QtMoko restarting because of a
bluetooth problem - is a simple race between that background rfkill
command and the rest of the qpe.sh script.

(It then makes sense that if QtMoko doesn't start quickly enough the
first time, because of bluetooth already being off, it will never start
on any further iterations.)

Here's what I see after commenting out that rfkill line:

- QtMoko starts up fine.  (This is not yet significant, though, because
  it often starts up fine anyway.)

- Bluetooth symbol is shown in the top line of the UI

- Diagnostic output:

Presumably, then, the right fix for this is either to ensure somehow
that the "rfkill block bluetooth" happens after QtMoko startup, or to
make QtMoko start up even if bluetooth is off.  The latter would be
better, because someone might have switched bluetooth off and then
choose to "Restart QtMoko".
