[Bug 1446987] Re: hpps (and other HPLIP components) should not crash in error situations

  Thread Previous • Date Previous • • Thread Next 
To the HPLIP developers at HP: See my changed bug description.

** Description changed:

+ The filter hpps crashes (Python Traceback) on a broken pipe on stdout
+ when the subsequent filter (the hp backend) errors out due to a network
+ problem (see comment #8). As Linux distributions have automatic crash
+ handling/reporting systems this causes annoying pop-ups which irritate
+ the users giving the impression of a more severe problem.
+ 
+ To the HPLIP developers at HP: Please check all components for possible
+ crashes in error situations.
+ 
+ Original report:
+ 
  I have a HP Laserjet pro 200 color MFP M276n which was configured and
  working normally. I have it configured both directly with an USB
  connection, and through the network with a fixed IP.
  
  Since a recent cups update (I believe), network printing does not work
  any more but the USB connection still works. When I try to print through
  the network I get a message telling me that the job has been send, and
  then I get a crash report. I don't know why apport is not intercepting
  the crash report, so I attach it manually here. In the "properties"
  window of the printer I see "Idle - Filter failed" and in the printer
  queue the job is "held".
