Follow Martin Pitt's instructions of comment #4, but where he says "print something", print 5 files from different applications and after each file wait until the job completes ("lpstat -o" does not have any output). When having finished the 5 jobs, attach your /var/log/cups/error_log file to this bug report. It then contains the logging of all the 5 jobs.
