[MapProxy] cache problem SRS31467

[Lars Schrader]

Hello,

I have a problem with the cache.
I tried to create a cache in SRS31467 because this is my most required SRS.

services.yaml -> srs: EPSG:31467

When I try to access the mapproxy with a GetMap-Request in SRS31467 I 
only get black picture with the attribution text insight.
There is no mistake in client.log or proxy.log.


After this I changed the srs-Parameter to:

services.yaml -> srs: ['EPSG:4326', 'EPSG:900913', 'EPSG:25832']

Now I tried the GetMap-Request in SRS31467 again. mapproxy created the 
cache in SRS900913 and transformed the cache to SRS31467 on the fly.

Is there a reason why it's not possible to create a cache in SRS31467?


Greetings, Lars
