Loading a message object without a text lead to a segmentation fault
in font_string_width since message->text is NULL. I'm appending a
small patch that fixed the problem for me.
I still have two (AFAIK known) problems:
- Trying to open the properties dialog via the menue I get the message
"This object has no properties" and double clicking on the object
gives a segmentation fault.
- Loading a saved file, everything is black, but ok after resizing.
