More crashes in menu complete

More crashes in menu complete

[Mikael Magnusson]

Here are two backtraces, i just did kill <tab> and pressed and
released shift a couple of times, doing complete-word and
reverse-menu-complete and got these two backtraces, the first sort of
sucks because i didn't have debug symbols when it crashed, but i
recompiled with and got at least the source line.

I think this depends on the detailed output of the matches.  It will
crash here if it's miscounted the number of matches that it can
fit on the screen.
