[Tilesathome] Problems rendering maplint layer for a few tiles

[Peter Pointner]

I noticed some tiles where rendering the maplint layer failed over and over 
again during the last 2 days.

I tried to find out what was happening, and in most cases the data downloaded 
from ROMA contained a way without the corresponding nodes. Checking the 
database, I found out that the way has been deleted meanwhile. Downloading 
from API did not have the problem, and so I assume that this problem will go 
away after some time.

But there are a few tiles which show a different problem, and downloading from 
API does not help. E. g. tile 1024 1638 fails over and over again. When I try 
to render the maplint layer, Inkscape (version 0.46) produces an invalid file 
maplint-z12-s0.png. The following split exits with error, and ImageMagick 
complains about a corrupt file.

I have no idea what could be done, so I give this to the list.
