[Tilesathome] isn`t numeric

[DeadlyAppearance]

I get at every tile at the last png an numeric error.
I haven`t change something at the conf file.
This looks right for me under windows:
## Linux workaround for inkscape internationalisation problems.
# Default is off (0) for windows
i18n=0

## Uncomment this for Windows installations in environments
# with "," as decimal separator
InkscapeLocale = german
