[Tilecache] An error occurred: Current x value ... is too far from tile corner x ...

[Christoph Lingg]

Thank you very much for your help, Dane!

Unfortunately I still get the same error:
 > An error occurred: Current x value 1050475.187500 is too far from  
tile corner x 1051768.941264

Maybe it is because of my chosen bbox? Do I have to consider certain  
intervals or can I set it like I want?

The other possibility I see is the projection. As I had problems, I  
chose the projection and settings that were exposed here in this  
working example:
http://www.mail-archive.com/mapnik-users@lists.berlios.de/msg01550.html

Does someone know where those errors come from and where i can search  
for more informations?

Thanks,
Christoph
