What I was doing when the application crashed:
I had an external USB disk (PSP in USB mode) connected and was copying multiple folders in serial. The disk became full and a set of "disk full - cancel, skip, autoskip) dialogues appeared in serial and I started to hit "autoskip" in each case. On hitting autoskipfor the fourth time, thecrash occurred.
