Summary: 2.10svn2517 crashes on debian squeeze with SIGSEGV

Initial Comment:
Any hints and pointers appreciated.
Installed todays osm package updates but that doesn't seem to have helped.
The hopefully relevant part of strace follows:

nice detective work.

the problem is that 0.5 is hardcoded:

src/gpsdrive_config.c
889:    g_snprintf(local_config.mapnik_input_path,
sizeof(local_config.mapnik_input_path),
890:            "%s", "/usr/lib/mapnik/0.5/input/");

Message:
OK, after being p*ssed of that it didn't magically fix itself... ;-)
I remembered that I only straced it and didn't gdb it.
I did and was surprised. I found the following:

Program received signal SIGSEGV, Segmentation fault.

#8  0x0807514b in gui_init ()
#9  0x0806d6a6 in main ()

Please notice that after using libmapnik0.6 all the time suddenly in #2 it
uses a file from 0.5.

Long story short:
dpkg --force-depends -r libmapnik0.5
fixes that and gpsdrive starts and works just fine. Just apt-get complains
about broken dependencies and wants to reinstall it.

I'm not sure, but I suspect that the dependency rule for libmapnik needs
some loving.
Anyone knowledgeable about this? As I don't know this well enough.

Kicking prio up a notch as this is a showstopper.

the shapefile name seems to have lost all but its extension. Anything
obvious which looks like that near the end of ~/.gpsdrive/osm.xml?

is the 300mb world coastline .deb installed?
