Alacarte crashes upon opening and will not display applications menu

[Jesse Talavera-Greenberg]

I'm using Ubuntu 15.04.

apt-cache policy alacarte returns:

alacarte:
  Installed: 3.11.91-2
  Candidate: 3.11.91-2
  Version table:

Last night I was removing some applications I wasn't using, via Synaptic. I don't remember which applications I removed exactly, but as soon as I did, alacarte suddenly broke. When I try to run it on the command line, I get this error:

jesse@jtg-ubuntu:~$ alacarte

Also, clicking the "Applications" menu will not display my list of applications. Nothing shows up. However, clicking "Places" right next to it works perfectly fine.

I'm using GNOME Flashback (or was it GNOME Classic? Forgot the exact name), dunno what version. I have been using it for months without any ill effect.

My ".config/menus/gnome-flashback-applications.menu" is totally empty.

EDIT: Seem to have found a workaround. http://ubuntuforums.org/showthread.php?t=2274544

Said workaround consisted of removing .config/menus/gnome-flashback-applications.menu (or backing it up, I guess).

Is this still problem?

I have the same problem.
