Thank you, Jbyvosges, for reporting this, and Curtis Gedak, for the solution. I had this problem also, and the fix worked for me. gparted would not open, despite uninstalling and reinstalling many times.
I had libgtk-2.4-1c2a already installed, and used Synaptic Package Manager to reinstall it. After this, gparted worked.
