KDE4 apps freeze when selecting File -> Print

Well, I've followed the Wiki directions and installed kdemod (KDE 4).  Currently, whenever I try to print by selecting File -> Print from within an application, the application just hangs (I never get a print dialog), and I have to kill it.  Cups seems to be set up properly through the web interface, and I can print test pages on both of my printers from there.  I'm on my second time installing Archlinux, because I could find absolutely no info online about this problem and thought I must have really borked something.

So, the second time around, I decided to keep a close eye on when the problem arose (installing only a couple programs at a time), since I didn't have the problem before installing additional software.  Each time I'd install a program, I'd reboot and then try printing from Konqueror.  Each time it would work, until after I installed truecrypt and yakuake, and then I began having the problem again.  I would suspect truecrypt rather than yakuake at the moment, but uninstalling both packages didn't fix the problem.  Furthermore, I can't remember if truecrypt brought down any dependencies sad

I seem to be the only person having this problem, if I can judge by the complete lack of info online about this (at least that I can find).

Re: KDE4 apps freeze when selecting File -> Print

Erm, last time I looked at KDE4 it didn't have any printing backend whatsoever. The feature plan for 4.2 mentions printing a lot.

EDIT: Ignore that. Printing worked fine for me with kwrite.
Take a look at the CUPS logs or ~/.xsession-errors.

Re: KDE4 apps freeze when selecting File -> Print

Okay, so when the application hangs while printing, no error messages are written to either the .xsession-errors or the cups log.  Opening the system monitor (CTL-ESC) I see no tasks taking up CPU or unusual amounts of RAM.  If I kill the frozen application, some lines are written to the .xsession-errors file, but I'm not sure if they are helpful or not.  Regardless, I have posted them below.

The application hangs immediately after selecting Print from the File menu.  After selecting Print, the file menu disappears, and a blank patch of grey is left in place of the menu--it never gets redrawn.  If I move any windows over other areas of the frozen application, those areas do not redraw either.

Here is what was written to my cups error log since booting my PC this morning.  The last item written to the log occurred two hours before I tried printing.

Re: KDE4 apps freeze when selecting File -> Print

Okay, I can print from GTK apps and OpenOffice.org, so it seems to just be KDE apps that are affected.  Any insights?

Re: KDE4 apps freeze when selecting File -> Print

Hiya,

Just thought I'd say that I'm getting exactly the same behaviour.

Any other app, including just plain old lpr can print just fine.

Furthermore:

# pacman -Ql kdemod-kdeutils-printer-applet
(no output!)
#

This can't be right...

Re: KDE4 apps freeze when selecting File -> Print

I really like the idea of Arch Linux, but I ended up installing Ubuntu because I needed to get work done.  I'll re-examine Arch and other KDE4 distros when KDE 4.2 rolls around.

Re: KDE4 apps freeze when selecting File -> Print

Hi guys

I also had this problem and am using KDEmod 4.2.2

I installed kdemod-kdeutils-printer-applet (which is not part of the kdemod group but is part of the kdemod-complete group) and that seemed to solve the problem

but the KDE application (Gwenview) that i used to print a test document still froze for a minuets  before giving me the print dialog screen and also froze for about a minute after i clicked print

anyone know why it is freezing or how to diagnose/solve this problem please post

those having this problem might be nice if you could see if this works and perhaps we could solve this problem
