PC build on wine.

Reproducable assertion failure:
System config -> fonts -> set customized fonts "on" -> klick edit on first item -> klick on font size value.
The result is the assertion pop-up from wine.

My guess is, that the font size should be better initialized, than just with "0". The xml dialog definition sets a value range from 1 - 200. that means 0 should be considered out of range.

The "0" leads directly to a tiny font by just entering the dialog and leaving with "ok". So there are possibly more benefits in initializing the font size correctly.
