[Tilesathome] Any ideas how to fix ./, problem (new windows client) ?

[Olf]

Hello !

Are there any ideas how to fix the './,' problem on the new windows 
clients that are set to
comma as decimal seperator ?
Currently I have to set my windows to "english" - setting to make the 
client run correctly.
Otherwise I get the error

'Rasterizing failed with runtime exception: Output file does not exist
at lib/Rasterize/Engine.pm line 58'
