Fast check with the 29-07-09 14:32 "a routing problem" problem, with
r1127 the problem is still there. Updated to revision 1131, used your
patch which (unfortunately) doesn't solve the problem *and* now there's
loads (well, 28 entries) of

SEVERE (RoadNetwork): Road Kasteeltuin (OSM id 7003822) contains a bad
arc of length 2,94m

length 2,94m

A couple of these are on the edge of a map, but this one for example

I did not check other routes. Please remember that the strange a,b,c
routing problem showed up in Mapsource but did not in my Garmin. I
didn't check my Garmin Nuvi here. Oh, and I don't know (so I can't test)
any other routing problems now but I wouldn't call that a problem :-) :-)

List follows below.
