Comment 7 for bug 331390

i can confirm downgrading of these packages does fix this...

libgtk2.0-0
libgtk2.0-bin
libgtk2.0-common
libgail18
gtk2-engines-pixbuf

and these are the packages i reverted back to....

libgtk2.0-0_2.15.3-0ubuntu2_amd64.deb
libgtk2.0-bin_2.15.3-0ubuntu2_all.deb
libgtk2.0-common_2.15.3-0ubuntu2_all.deb
libgail18_2.15.3-0ubuntu2_amd64.deb
gtk2-engines-pixbuf_2.15.3-0ubuntu2_amd64.deb
