problems with ghash.c (?)

[Gergely Pongracz <Gergely Pongracz eth ericsson se>]

Hi!

I have modified a once working GTK based code, and as a result,
now got the following error message:

GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup):
assertion `hash_table != NULL' failed.

Gtk-WARNING **: gtk_type_create(): unknown parent type `21'.

GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup):

Segmentation fault (core dumped)


This is quite strange, because in that rows of the code, I did
not modified anything. (The row, on which the code collapses is a
simple window creation:

window1 = gtk_window_new (GTK_WINDOW_DIALOG);

Does anybody have any idea, what is going on?
I don't have more. :(

Thanks in advance, and please reply me in direct mail, because
I'm not the member of this list!
