 this instantly triggers the assertion. 
Note that it triggers this even in a non-mule emacs...!

For me it triggers on

Fatal error: assertion failed, file insdel.c, line 1117, ( retval) >= BI_BUF_BEG (buf)
&& retval <= BI_BUF_Z (buf)

which is not surprising given that we are messing with the
narrowing...
