Hi Henrik,

I've done a few tests with the current svn version today, and it looks good.
I haven't tried the maps on a GPSr yet but at least they don't crash  
mapsend ;)
Most polygons are rendering now. I haven't tested the bounding box or  
pgsql yet.


On another note, I've been getting an error for a while on one  
particular map I've been building:

magellan/DBUtil.py:190: DeprecationWarning: 'H' format requires 0 <=  
number <= 65535
   return apply(struct.pack, (structendian+types,) + data)
magellan/Layer.py:646: DeprecationWarning: 'H' format requires 0 <=  
number <= 65535
   return struct.pack(prefix+types, *data)

I *think* this is because there are more than 64k  
residential/unclassified  roads in the osm extract going in to a  
single layer.
Is this a limitation of the magellan map format, or in pymag?
In an attempt to overcome this in the past I've split the roads into  
multiple layers, and that builds successfuly.
The map can be opened in Mapsend and Vantagepoint, but locks up GPSRs  
(tested on half a dozen explorists) as soon as you select the detail  
map.
I don't know if this is related or a different problem.
Any hints on diagnosing the problem other than trial-and-error  
exclusion of objects?

Cheers,
Josh
