Can't print messages with attachments from Kmail

[Lowell Johnson]

After the upgrade to Kubuntu Jaunty 9.04), messages with attachments won't print from Kmail to a remote (shared) printer through CUPS.  No warnings are displayed, just a quiet failure to print. This worked in Intrepid (8.10)(according to my wife). Mail messages without attachments print fine, and direct connecting the printer prints message with attachments OK.  The type of attachment doesn't seem to make a difference.

We have two systems (my wife's desktop with a wired connection running Jaunty and my laptop with a wireless connection running the Alpha 6 of Karmic 9.10) that both exhibit the problem. We have two HP printers (HP LaserJet 1320 and HP PSC 2355) attached to my desktop (acting as a household server, running Kubuntu Hardy 8.04 KDE 3.5.x). The choice of printer makes no difference regarding the issue.

Printing the "problem" messages to PDF works fine. So it seems to be some sort of Kmail/CUPS issue, but I'm running out of ideas of where to look or what to try next.

The /var/log/cups/page_log file (on the client machines) for the failed print jobs contains the following:

  hp1320 ldj 34 [08/May/2009:18:13:06 -0500] 1 1 - localhost
  hp1320 ldj 34 [08/May/2009:18:13:28 -0500] total 0 - localhost

For successful print jobs, this looks like

  hp1320 ldj 33 [08/May/2009:18:11:04 -0500] 1 1 - localhost
  hp1320 ldj 33 [08/May/2009:18:11:25 -0500] total 1 - localhost

The value for "total" varying between 1 (for successful, single page prints) and 0 (for unsuccessful prints) is the only clue I've found. I didn't see anything that looked unusual in the /var/log/cups/access_log file, and there is no error_log.

Thanks for any ideas or suggestions!
