Comment 6 for bug 499754

I managed to fix it. I downloaded a new alacarte source package and compiled the source code myself. I can now edit any menu entry in alacarte.

If anyone needs to fix alacarte in Ubuntu Lucid (alpha 1) (gnome-desktop), because you are unable to edit the entries in the gnome menu, see below.

I got alacarte from gnome 2.29.4 - alacarte version 0.12.4 found here:
http://www.icewalkers.com/download/GNOME/1075/dld/

I think the dependencies were intltool and libgnome-menu-dev
(when you run ./configure it will tell you)

./configure
make
sudo make install

you might need to reboot the system, if not log out and back in again.

Also, I was advised that *.desktop files are not present in the ~/.local/share/applications folder by default, so I am mistaken about that part in my earlier post.

Probable Bug Solution:
I think alacarte needs to be recompiled for i386 desktop (Lucid alpha 1) before alpha 2 is released.
Thanks,
