Just tonight my Applications menu went blank. No categories or applications are listed, not even the divider lines (just the gray on the left and white on the right). The only things I did before this happened were update knips and install emelfm2 (to locate where the xmms skins were installed to). I uninstalled emelfm2 thinking maybe that messed things up. At the same time I noticed I once again also had the xmms font problem where none of the main popup menu text was showing up (maybe a GTK problem?). I even tried removing some larger applications because running xmms from the commandline complained about no space left on the device, but that did not help either of the two situations/issues.

Is it possible that installing emelfm2 overwrote some GTK libraries/other files used by the Apps menu and xmms that didn't get reverted back after uninstallation?

Edit: I've also tried restarting twice.
