We're talking about a really long time here (many minutes), whereas the 
diagram printed quickly before. In the reduced version that works, it's 
quite quick to print, whereas the buggy version doesn't do anything for at 
least five minutes.

I guess I mean that the freeze is really a crash, as the Dia window stops 
updating and becomes completely unresponsive. Looks like the software is 
in a loop waiting for somehing.

Ok, I'll do that tomorrow so you can see if you can replicate.

On dia screen (symbolically):           On (working) printout:

It's not urgent (I hope:-).

Btw, is it possilble to open (most) diagrams created with 0.97 in the 
older version of Dia?
