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? On Fri, 2014-09-12 at 10:47 -0500, Blake McBride wrote: > Here are the steps that reproduce the problem: > > > 1. Execute aplwrap > > > 2.
