this might be related to another crash, which is quite easy to
reproduce: try closing a main patch containing a [nogop] abstraction,
which in turn contains a [gop] abstraction, while [nogop]'s window
is closed, but [gop]'s one is open...

#0  0x08064732 in glist_findrtext (gl=0x8111d48, who=0x81119d0) at 
g_rtext.c:332
332         t_rtext *x = gl->gl_editor->e_rtext;

bt is different, so it might be another bug, but both cases look
somehow related, at least conceptually.
