Is freeze and crash the same thing for you? (I've seen single rendering of diagrams take minutes, but not for the cairo backend. See for the messy details.)

We're talking about a really long time here (many minutes), whereas the diagram printed quickly before.
After looking into this with you example that time is even infinite ;(

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

It definitely should not, but indeed it does ;( From my current analysis this is a bug in cairo:

Yeah, it can be reproduced with every renderer using cairo, also the antialiased display renderer. Thus my mentioning of *completely* disabling the cairo plug-in as a temporary measure.

It is enabled by default, look for a file <original file path>.autosave


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

Yes, but that can create subtle data loss, because Dia versions are silently throwing away stuff they don't understand. One issue from the top of my head is the incompatible change of "UML - Association".
