Ok.  I'll do that.  Meantime, I closed the terminal because I wanted to 
edit the bash history files.  Two menu-editor windows appeared from 
nowhere, so I opened the terminal again and :

- - - quote - - -
Starting program: /usr/bin/xfce4-menueditor
Reading symbols from shared object read from target memory...(no 
debugging symbols found)...done.
Loaded system supplied DSO at 0xffffe000
(no debugging symbols found)
ditto umpteen times
- - - end quote - - -

When I attempted to navigate into /usr/lib, the following appeared in 
the terminal:

- - - quote - - -
Program received signal SIGSEGV, Segmentation fault.
0xa75b846a in strcmp () from /lib/i686/libc.so.6
- - - end quote - - -

I watched the hour glass turning for 2 minutes and killed the menu editor.

I should add that the same problem occurs when I try to enter /lib in 
the menu editor.  These attempts occur when, to choose an icon, I select 
"image files" and get a navigator dialogue.

I'll try the other method asap, probably tomorrow.
