I had also a case where there was a too long arc. Have lost the exact
error massage because of too many "too many POIs in group" messages. It
was some ferry route between France and Corsica.

I've applied your patch and will try the compile again now (will take
two hours). Meanwhile I've created a small patch which reduces the noise
of these "too many POIs in group" messages. If you find it useful, I
will be pleased...

Cheers
Andre
