Re: [Bug-apl] aplwrap assertion failures

[David B. Lamkins]

I reached similar conclusions. It seems that copy/paste tickles this
bug.

Copy, then paste, then evaluate, then click the close box: this is
enough to give me GTK+ errors and even stack dumps.

These are probably the important clues:

GLib-GObject-WARNING **: invalid unclassed pointer in cast to
'GtkTextView'
(aplwrap:29325): Gtk-CRITICAL **: gtk_text_view_scroll_to_mark:
assertion 'GTK_IS_TEXT_VIEW (text_view)' failed

gtk_text_view_scroll_to_mark() appears (in aplwrap code) only in
scroll_to_cursor(). Is the cast in that function incorrect?
