One of our users reported this error when launching any application using pycairo:
Traceback (most recent call last):
  File "exaile.py", line 44, in <module>
    import gtk, gtk.glade, pango, dbus
  File "/var/lib/python-support/python2.5/gtk-2.0/gtk/__init__.py", line 48, in <module>
    from gtk import _gtk
  File "/usr/lib/python2.5/site-packages/cairo/__init__.py", line 1, in <module>
    from _cairo import *
ImportError: /usr/lib/python2.5/site-packages/cairo/_cairo.so: undefined symbol: cairo_clip_extents

This bug has been reported to Ubuntu too: https://launchpad.net/bugs/129816/.

Thank you.
