Did the GPS icon of the N900 itself indicate that it had a position? It blinks
while waiting for a position (enough satellites seen) and stops blinking once
it has enough satellites. I mean the white icon on the top-right of the battery
icon in this screenshot:

Receiving an initial GPS position can be problematic in both situations you
describe: In closed rooms, only a few satellites are typically seen, so GPS
often does not work. When moving while not having an initial fix, the
satellites seen change shortly (due to occlusions by e.g. houses). Therefore it
can take quite long to get the initial fix. To work around it, have the device
at a fixed position where as much as possible of the sky can be seen.

Maybe we should add a small widget that shows how many and which satellites are
being seen by the device currently. This allows to adjust the position
initially slightly for optimal satellite visibility to have it get the needed
initial fix. Currently our plugin interface does not allow for this kind of
information though.
