If you load lib/font.c and enable LARS_TRACE_MESSAGES (on line 75), then you
will get lots and lots of messages in your terminal when you run Dia, but
that will help you to locate the problem. I'm worried it's my code :-(
Please, if you can, do this and send us the output. You may also wish to do
a ./configure --enable-debug and then make clean in the lib directory.
