Comment 23 for bug 1347272

@ Alistair,

I don't explicitly have Unity installed (I'm on Xubuntu 14.04), but a search via synaptic shows that I do have these Unity-related packages installed, possibly as dependencies for some piece of software I was compiling:

gir1.2-unity-5.0 7.1.4+14.04.20140210-0ubuntu1
libunity-protocol-private0 7.1.4+14.04.20140210-0ubuntu1
libunity-scopes-json-def-desktop 7.1.4+14.04.20140210-0ubuntu1
libunity9 7.1.4+14.04.20140210-0ubuntu1
unity-gtk-module-common 0.0.0+14.04.20140403-0ubuntu1

unity-gtk3-module 0.0.0+14.04.20140403-0ubuntu1

Also, I don't have any overlay-scrollbar packages installed, but I do have these dbusmenu packages installed:

gir1.2-dbusmenu-glib-0.4 12.10.3+14.04.20140612-0ubuntu1
