Debug messages is completely disabled in the distribution .deb. Only critical errors are reported on the command line. You can rebuild maemo-mapper with the DEBUG macro defined to get a lot of debug (most function entry points, plus some other debug), and you can enable the vprintf macro to get even more debug.

I've not yet plowed through the source (mmm, one big shiny file) but anyone (gnuite <hint> ;-)) know how good it is with buffer overflows etc.? e.g. if it gets dodgy data from the GPS?
The NMEA reading is done with g_io_channel_read_chars(), and a "max # of chars" parameter is passed to the method, so it's unlikely that the char buffer is being overrun. But I could be wrong...

Which GPS receiver are you using?

Has anyone else had problems with that receiver?
