Release UI by opening a VT, no need to log in. Then immediately return to UI with "ctrl-alt-F7"
LO 4.1.2.3, KDE4.11.2, Kernel3.11.0-13
Quoted from first comment:-
"Moreover, the freeze includes the whole X.org UI, including desktop. There's no way to kill LibreOffice from the GUI. However, CTRL+ALT+F -keys still work so one can go to a VT and kill libreoffice from there, and the UI is released."
