 I have just seen the same thing on a RELENG_5 system as of Oct 24th. In
 this case it was Umbrello, which comes with devel/kdesdk3; Umbrello
 crashed (application bug, AFAICS), and when I closed the window that
 showed the backtrace, the process remained in state 'STOP', according to
 top(1).
 
 I don't know if the application's backtrace can be of any help here, but
 just in case:
