Public bug reported:
I printed something, afterwards I wanted to print again, but the printer did
not receive the print job, so I cancelled the job and tried to start it yet
again. Unfortunately it did not resolve the situation.
So I cancelled the print job and while at it, I changed the driver from
driverless to hpcups to allow me a more precise paper selection.
Afterwards I succeeded to print. Somewhere in the middle of all that a
crash happened (this is the relevant excerpt of the .crash file after
running apport-retrace):
