Has happened to me twice so far on a recent install of Lubuntu 13.10 with a synaptics touchpad.
Only changes from default touchpad configuration:
syndaemon -d -t (disable touchpad tap and scroll when typing)
synclient LockedDrags=1 HorizTwoFingerScroll=1
The most recent scrolling lock occurred when a PDF was loaded in Document Viewer that put some strain on the system. The computer had been suspended and resumed prior to this.
