[mkgmap-dev] How to solve/debug weird problem

Thu Jan 13 20:55:36 GMT 2011

Hello

I kind of recognise the symptoms, but the cause could be just about 
anything.

>      [apply] SEVERE (Polyline): /home/osm/build/59420066.osm.gz: Problem
> writing line (class uk.me.parabola.imgfmt.app.trergn.Polyline) of type
> 0x10a0c containing 2 points and starting at

I think this error is appropriate, except that the real error has been 
caught in order to print the error message, so hiding the real error.

If you could apply the attached patch and run the same thing you should
get a better error to send me.

Alternatively it might be obvious by looking at the url printed in the 
messages if the problem is in the data - look for road with very long 
segments or something obviously wrong with them.
