[Peter]

I'll look into it. I don't have a qt that recent I don't think, so that's probably the problem.

In the mean time, try doing "make clean" and then make and let me know if there's still the same crash.

[v4hn]

This segfault happens when the connection is closed.
Commenting out both setModel(0)-lines in ~Room removes the segfault but might introduce other problems...
