Distribution/Version: Gnome 2.10

... maybe by design. It probably should be disabled as claimed 
in bug #153609. Here a simple way to reproduce:

$ gdb --args /opt/bin/dia --g-fatal-warnings samples/render-test.dia
samples/Self/dia-core.dia

[Play a little with the two diagrams, e.g. ctrl-e, move the window,
 change, wait 10 seconds]

Can't get it to crash or show the old behaviour with current CVS. I am willing
to have the cache be optional, so that people working with lots of text have a
chance of making it fast.  It may also depend on the version of GTK, I'm using
2.4.9.

Cache ifdef'd out.  Marking this as enhancement, as fixing it would enable speed
improvement.

With the new rendering aproach the old font cache is gone which make this obsolete.
