[Therion] cavern exit code 256

[Benedikt Hallinger]

I found it, the following error is reported by cavern:

The source giving causing it is:

If i remove the standard-deviation zeros, cavern stops to complain.

The reason was that the entrance location was measured by public service 
against official grid by theodolite and as such is "perfectly correct".
How can i give this information? Am i forced to use some minimal positive 
fraction? (eg. "0.00001"?)
If yes, could this be an cavern bug?
