Description Tom Kijas 2009-12-22 22:33:37 UTC

Version:           1.0 (using 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2)), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.31-11-generic

Few days I updated from KDE4.3.4 to KDE4.4 beta and since that time, I have no chance to change printer settings in system settings. It shows me "The service 'Printer Configuration' does not provide an interface 'KCModule' with keyword 'system-config-printer-kde/system-config-printer-kde.py'The factory does not support creating components of the specified type.

Possible reasons:
-An error occured during your last KDE upgrade leaving an orphaned control module
-You have old third party modules lying around.

Check these points carefully and try to remove the module mentioned in the error message. If this fails, consider contacting your distributor or packager." Please help me what to do with that. Thanks

Comment 1 Tom Kijas 2009-12-22 22:36:46 UTC

I must also say that I tried to do sudo apt-get autoremove and sudo aptitude autoclean but nothing helped. I also uninstalled and reinstalled the system-config-printer-kde...

Hi,

I see the same behaviour on a full updated Fedora rawhide (KDE 4.3.85). Running from the command prompt shows the following messages:

Hi,

I've just updated to (KDE 4.3.85 (KDE 4.4 Beta2)) and I've encountered the same error described.

I'm using Ubuntu 9.10 and packages from kubuntu-ppa/beta.

Here is the output when running systemsettings from console:

Hi,

I've just updated to (KDE 4.3.90 (KDE 4.4 RC1)) and the error is still there.

Comment 5 Raphaël G. 2010-01-16 21:03:28 UTC

Error still here with KDE 4.3.90 on Kubuntu Karmic

Comment 6 jajaX 2010-01-16 23:58:28 UTC

Hi !

same problem for for me (kubuntu 9.10, KDE 4.4 rc1)

Fix running with Python versions greater than 2.5. NotImplemented is a constant, not an Exception, so the code should return rather than raise. This should have no impact on Python  2.5 or older.

Comment 9 Martin Kho 2010-01-25 14:28:37 UTC

Hi,

I replaced the old options.py for the new one. Removed all compiled sources (*.pyc and *.pyo). Did run:
"python /usr/lib64/python2.6/compileall.py ." and
"python -O system-config-printer-kde.pyc"

Something is still not well, or do I something wrong?

Now starting systemsettings -> Printer Configuration gives:

Comment 10 Martin Kho 2010-01-31 10:04:42 UTC

Hi,

Issue in comment #9 was introduced in r1009674 (copy & paste issue? :-)). I've created a patch to correct the AttributeError.

I hope the patch is correct.

Comment 12 Kevin Kofler 2010-02-10 23:42:16 UTC

Offending revision: http://websvn.kde.org/?view=rev&revision=1009674
The fix looks correct to me, can it please be applied? We'll also want to backport it to the Fedora packages.

Comment 13 jajaX 2010-02-11 22:23:05 UTC

Hi !

it's ok for me under kubuntu 9.10 with kde sc 4.4.

thanks you ;)
