Public bug reported:

I'm upstream developer of fityk and I've got several reports  from Ubuntu 14.04 users that the program crashes when using Unity. The workaround is to set UBUNTU_MENUPROXY=0.
To reproduce:
apt-get install fityk
fityk
and zoom in using a mouse.

Valgrind shows this:

The program creates radio item in a submenu, later deletes it and
creates a new radio item in the same place - and segfaults at this
point.
