Yeah, the extra-testing version is not compatible with Qt 4.7 for some reason ... I'll push 0.3.0 as soon as it's stable.

So, some questions:

What exactly happens when you launch it without ovi map started ?
Do you see the GPS related messages before the crash ?
Station selection is still automatic ?
Is the gps icon blinking in the task bar ?

Are you sure PR 1.3 upgrade is complete (apt-get upgrade doesn't try to install any new package) ? When I upgraded mine, a lot of packages were not totally upgraded, I had to fix it with dpkg --configure -a.

If gdb is installed on you N900, could you get me a backtrace ?

Thanks !
