Arch Linux

Description:
Since upgrading to cups 1.4.7, I'm unable to print to a network printer. The CUPS backend (in my case "socket", in other cases "lpd") crashes. Downgrading to 1.4.6 solves it, so I don't think it's a driver issue. I did try to delete and re-add the printer with no effect.

This had a forum thread https://bbs.archlinux.org/viewtopic.php?id=122482 but apparently no one bothered to report it here. My printer, like the last poster of the thread's, is an HP DeskJet 6940 using the hpijs driver, network attached using HP JetDirect.

Additional info:
* package version(s)
cups 1.4.7-2
hplip 3.11.5-1

* config and/or log files etc.
This output is for a CUPS test-page job, which is much simpler to read than for an actual print job.

Steps to reproduce:
Configure a network printer (HP JetDirect socket or generic lpd are known to reproduce this) and then send a CUPS self-test page.
