I'm having problem tracing this problem down, it seems that in my sample
program it doesn't happen, but happens in the real program. I must admit
that the program has somewhat a spaghetti structure since I am only
getting to know java-GNOME and GTK, so I'm experimenting with things and
add more and more on top.

The problem seems to occur even when references to the TreeModelFilter
are replaced with references to the TreeStore, only then it is harder to
produce. Can someone shed any light on what the error is supposed to
mean, and what it might be related to?

Thanks,
 Igor
