I've been building maps for Iowa for a while with great success, but today I tried adding in Minnesota since I'll be travelling to the Twin Cities for the holidays. I ran into this issue though:

SEVERE (Polyline): Problem writing line (class uk.me.parabola.imgfmt.app.trergn.Polyline) of type 0x1c containing 3 points and starting at http://www.openstreetmap.org/?lat=49.00046&lon=-97.22862&zoom=17 SEVERE (Polyline): Subdivision shift is 0 and its centre is at http://www.openstreetmap.org/?lat=48.97566&lon=-96.19088&zoom=17 SEVERE (Polyline): deltaLong = -48362

I'm using an .osm file split out of the 091216 planet file using a snapshot of osmosis from Nov 28th, split up using splitter rev 103 and mkgmap 1436.

I had the same problem recently and it was due to a long way (more than 800 km) with no intermediate nodes. Adding some nodes to the way solved the problem. You'll continue receiving the message until you add enough nodes.
