bug#36461: 11.90.2.2017-07-25; xemacs21.4.22 mule, problem with window too small (auctex 11.92)

[Uwe Brauer]

Hi

I installed a colleague who is running xemacs21.4.22 on Ubuntu 16.04 the
latest auctex version which is compatible with xemacs, namely 11.92.

While everything works fine when using keys (like C-c C-c)
when accessing the latex commands via the menu the following error pops
up 
Debugger entered--Lisp error: (error "Window height 0 too small (after 
splitting)")
   split-window(nil 17)
   mouse-read-file-name-1(file-name-history "Master file (default this 
file): " nil "~/TODO/docencia/prufungen/prueba.tex" nil nil 
read-file-name-internal)
   byte-code("..." [initial-contents must-match default dir prompt 
history mouse-read-file-name-1 completer] 8)
   read-file-name-1(file file-name-history "Master file (default this
