jockey-kde crashed with ImportError in <module>()

[Ryan VanSickle]

This actually appears to be a kdecore issue. Output from jockey-kde from the command line:

$ jockey-kde
Traceback (most recent call last):
  File "/usr/bin/jockey-kde", line 28, in <module>
    from PyKDE4.kdecore import *
ImportError: No module named kdecore

I also saw a similar issue running apport-bug:
Could not import module, is a package upgrade in progress? Error: No module named kdecore

I am running the kde desktop so I would expect that the applications using the kde libraries would also run.

[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #263017. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

[Jonathan Thomas (echidnaman)]

A fix should be arriving with the next batch of updates which are building at the moment.

[Jonathan Thomas (echidnaman)]

Mm, the kdebase-workspace upload is being held back until kde4libs can be uploaded, but once it builds it'll delete the old dist-packages for PyKDE4, or so sez Riddell.

[Martin Pitt (pitti)]

Bug 450851 was marked as a duplicate of this. However, the real problem seems to be in kdebindings, not in kdebase-workspace. Also, this bug was marked as fixed without referring to a changelog. What was fixed, and where? At least, python-kde4 needs a preinst script which cleans up the old __init__.pyc from pycentral (since the package was switched to pysupport). I don't see that on -changes@ yet?

Thanks!

Is it related issue?

http://bbs.archlinux.org/viewtopic.php?pid=632942

Or, resuming, python-kde4 isn't in sync with python-qt4. As a result, python-written plasmoids don't work. Also decribed here:

http://kde-look.org/content/show.php/Complex+Plotter?content=111400

"seems like distro has updated sip/pyqt4 but not pykde4 packages and sip api doesn't match".

[Jonathan Thomas (echidnaman)]

Yes. There's an old copy of some PyKDE4 stuff hanging around in a directory kdebase-workspace was responsible for. Once the updates are unleashed this will be fixed.

[Jonathan Thomas (echidnaman)]

Oh, I missed your comment Martin.

Basically the python plasma bindings in kdebase-workspace were the only thing left that was keeping /usr/lib/python2.6/dist-packages/PyKDE4 around. 4:4.3.2-0ubuntu2 should have fixed this, but due to some kde4libs troubles kdebase-workspace 4:4.3.2-0ubuntu3 was published before kdebase-workspace 4:4.3.2-0ubuntu2 was published.

According to Riddell, this kdebase-workspace update should remove /usr/lib/python2.6/dist-packages/PyKDE4 entirely.

[Martin Pitt (pitti)]

Hello Jonathan (both :) ),

thanks for the heads-up. With today's upgrades, apport-kde works
again. Thanks for sorting it out!

I just got a ping from Julian Edwards that he still has the bad .pyc file on his system. Apparently this didn't get cleaned up yet?

[Jonathan Riddell (jr)]

kdebindings 4:4.3.2-0ubuntu3 adds a postinst script to remove the old .pyc file

[Pedro Villavicencio (pedro)]

There's at least 6 new duplicates with Lucid showing the same pattern, apport marked those as duplicate, I'm thus setting this as Triaged. Jonathan may you please have a look into this? Thanks.

[Jonathan Thomas (echidnaman)]

This is a transient error that can show up when sip breaks abi compatibility. Should be fixed by final now.
