The symptoms indicate that maemo mapper goes into an infinite loop
somewhere.
Random thoughts:
* I have not registered my GPS anywhere in the control panel. I've
heard that N800 comes with gpsd that allows multiple applications to
use the GPS at the same time. Perhaps Maemo Mapper instead of using
gpsd tries to access the GPS directly and they conflict?
* Does your device send proper NMEA sequences? There should be a way
to test it with rfcomm bind rfcomm0 XX:XX:XX:XX:XX followed by
cat /dev/rfcomm0. If you get binary gunk instead, then your GPS is
switched to some other protocol (e.g. SiRF) and Maemo Mapper does
not understand it. It is possible that these unexpected messages
may trigger a bug in Maemo Mapper's parser causing it to loop
forever.
The best way to figure out what is happening would be to build
maemo-mapper with debug symbols and attach gdb to it when it starts
looping.
