For me this happened when I installed a program, then immediately decided that I don't want it and hit the Remove button that shows up (while it was still installing) it then removed the Remove button or grayed it out, not sure anymore - and after the progress bar on the item was gone the installer crashed and brought me here! Hope it helps tracking it down!
