[pygtk] gtk_text_layout_real_invalidate: assertion `layout->wrap_loop_count == 0' failed

[N. French]

In my multi-threaded GTK app I see this at startup:

nw_gtk.py:68: GtkWarning: gtk_text_layout_real_invalidate: assertion
`layout->wrap_loop_count == 0' failed

The line it refers to is the insert() call in the below function.

    def push(self, text):
        """Writes text to the buffer."""
        end_iter = self.buffer.get_end_iter()
        self.buffer.insert(end_iter, text)
        self.tv.scroll_to_mark(self.buffer.get_insert(), 0)

self.buffer here is a gtk.TextBuffer from a gtk.TextView.  The TextView
is set to wrap lines.

This is on GTK 2.6:

gtk2-2.6.7-4
pygtk2-2.6.0-2
pygtk2-devel-2.6.0-2

Any ideas?  I didn't find anything googling this error.  Well, a lot of
people have this problem but I didn't find any solution other than to
call gtk.threads_enter and gtk.threads_leave around GTK calls in
threads (which I am doing).
