NPE when attempting to combine ways

[anonymous]

If you look at this bit of map:

​http://www.openstreetmap.org/?lat=53.026997&lon=-2.78187&zoom=19

Select the tiny segment just below the fork and the segment below that and try and
combine them with 'c' and you get:

Just noticed that if you only download the region specified above, the ways are combined without
a problem.

But if you have a much larger region, there is a problem. Now I wonder if this is because those ways are members of a route relation "Bishop Bennet Way" and when I edit the much larger region, there are multiple relations with the same name included in that region.

Could not reproduce. Please attach OSM file which allows to reproduce problem.

It's probably too big to upload (20MByte). Here's the script I use to download the area from XAPI, I hope you use a *nix machine and can run this.

#!/bin/sh

BOUNDS=-3.25,52.75,-2.5,53.2

#HOST=osmxapi.hypercube.telascience.org
HOST=www.informationfreeway.org
#HOST=xapi.openstreetmap.org

if wget -N ​http://$HOST/api/0.6/map?bbox=$BOUNDS -O local-area.osm.tmp ; then

mv -f local-area.osm local-area.osm.last
mv local-area.osm.tmp local-area.osm
sed -i 2s/version=\'0.6\'/version=\'0.5\'/ local-area.osm

else

rm -f local-area.osm.tmp

fi

Err, that script didn't come out right. I will attach the file.

In r1621. The problem was XAPI not the size of data.
