While I don't have added such a check and the talkback yet I have fixed
a related bug that caused error information not being passed back to the
caller, in this case the rendering did not abort when xml2svg failed, so
tilesGen.pl exits when the perl::GD module can't find the image.

This should do away with this bug as well, but I'll add checks and maybe
talkback as I find the time to do so.
