I wrote a kross script that update twitter status when a download is complete.
It worked on kubuntu 8.10 with kde 4.2.2 from svn and ktorrent 3.2.1 from svn too.
When i upgraded to kubuntu 9.04 the script stops to work,

Code: Select all

ilich@azurill:~$ ktorrent --version
Qt: 4.5.0
KDE: 4.2.2 (KDE 4.2.2)
KTorrent: 3.2.1
ilich@azurill:~$ python --version
Python 2.6.2
ilich@azurill:~$ kross --version
Qt: 4.5.0
KDE: 4.2.2 (KDE 4.2.2)
Kross: 0.1


using the kross command line tool i noticed that the problem was loading the twitter library (python-twitter on ubuntu), digging in the traceback seems that the problem is the loading of ssl python library.

Code: Select all

Original exception was:
TypeError: Error when calling the metaclass bases
    module.__init__() takes at most 2 arguments (3 given)
Kross: "PythonScript::Destructor."

Loading of twiiter, urllib2 or ssl python libraries in normal python script it gives no problem and works. (I get only a warning on twitter libraries)

Is this a bug or a problem of my box?

Don't know, it should work, if it also works in a normal python script.

Are you sure you can actually use the twitter module in a normal python script ?

Yes it works and you can see here

But i think that the problem depends on ssl library.
Someone can try a script with only:

Code: Select all

import Kross
import ssl #or urllib2 that is the library needed by python-twitter


and run:

Code: Select all

ilich@azurill:~$ kross script.py
