[Tilecache] Segmentation fault ERROR when run tilecache_seed.py

[Dane Springmeyer]

Petrus,

Actually, I think I know the problem.

On Ubuntu Karmic do:

sudo apt-get install python-cairo

Then let me know if that works (with the python-mapnik package in  
Karmic). It looks like a bug specifically in the package, as python- 
cairo is a missing dependency.
