Details:

I've had this happen on several occasions now, where I create a new function,
run it, get an error, then try to open it via the keyboard edit file shortcut
(ctl E is the default, but I have changed it...), and then octave immediately
crashes. It has been very repeatable.
The shortcut works on files without an error. Typing "edit file..." works
without crashing.

Here's an example:
save a file editCrash1.m with 

function [a] editCrash1()
    a=1;
endfunction

in the editor type editCrash1 somewhere, click on it and type the edit
keyboard shortcut (e.g. ctl E). Octave crashes.

2nd example:
save a file editCrash2.m with 

function editCrash2()
    a=;
endfunction

in the editor type editCrash2 somewhere, click on it and type the edit
keyboard shortcut (e.g. ctl E). Octave crashes.
