[Tilecache] Current y value 5009377.084000 is too far from tile corner y -0.000800

[Christoph Lingg]

Hi list,

I had a running tilecache map server and recently I updated tilecache to the newest version. Using the same tilecache.cfg as before, 50% of the tile requests are running as before, but the other half end up with an error like:
> An error occurred: Current y value 5009377.084000 is too far from tile corner y -0.000800
I am struggling around with this error for a couple of hours now, having tried out a lot of parameters. My configuration is very very basic:

OpenLayers:

Tilecache:

> spherical_mercator=true
> tms_type=google


Has there been changed something since the last tilecache updates? I am not able to explain the origin of this error? Does anybody has a hint?

Thanks,
Christoph
