GtkTextBuffer crashes

[AlannY <m alanny ru>]

Hi there.

I have trouble in my program.

First of all, I'm using latest GTK and got many assertion in console
when using GtkTextBuffer.

Second. I have 2 threads. First one is a gtk_main_loop. Second one is my
(pthread) thread. In second thread I'm trying to set this:

gtk_text_buffer_set_text(window.buffer, "", -1);
gtk_text_buffer_get_start_iter(window.buffer, &iter);
gtk_text_buffer_insert_with_tags(window.buffer, &iter, "Some text", -1,
bold, NULL);
gtk_text_buffer_insert_at_cursor(window.buffer, "Another text", -1);

Then I got many assertions, aborts and segmentation faults:

Gtk-ERROR **: file gtktextlayout.c: line 1113 (get_style): assertion
failed: (layout->one_style_cache == NULL)
Gtk-CRITICAL **: gtk_text_layout_real_invalidate: assertion
`layout->wrap_loop_count == 0' failed

Is there any idea on how to solve this problem?
