Public bug reported:

Binary package hint: python-qt4

python-qt4 (PyQt4) is broken on Lucid Lynx. This has been reported in
bug #561303 and a fix was issued for Maverick, but the bug was closed
without fixing the problem on Lucid, which is a long term support
release. I am opening this bug to track the resolution of the problem
specifically for Lucid Lynx.

The problem is present in the current package version on Lucid
(4.7.2-0ubuntu1). It can be observed even on the simple built-in

$ python /usr/share/doc/python-qt4-doc/examples/dialogs/standarddialogs.py 
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such file or directory
QFileSystemWatcher: failed to add paths: /home/ubuntukaka/.config/ibus/bus
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon 
Segmentation fault

This is not only a cosmetic issue; programs are failing, which affects
the exit status, and it also breaks any kind of insulated unit testing.

As per discussed in the other bug report, the problem was solved in
version 4.7.3 ( http://article.gmane.org/gmane.comp.python.pyqt-
pykde/18961 ).

For reference, the corresponding bug report on Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=583951 (they seem to have
bumped the version to 4.7.3)
