Depends on: 270529
This could just be about trying to remove an entry which is not in the table? Is GetEntry returning 'nsnull' or a pointer to another entry? Can someone with the debugger find out what GetEntry is returning in this case? Or, just like bug 270529, this could be a race-condition thing?
