Hi there. I have the exact same problem. I only have the "maemo" and "maemo extra" repositories enabled, tried installing and uninstalling via the cleanup tool many times. I also tried the python symlink and manually uninstalling several apps like st5150 suggested, but nothing worked so far. I would really like to try canola, but am not willing to format my N810. This is what I get, when running canola:

Traceback (most recent call last):
File "/usr/bin/canola", line 18, in <module>
import ecore
File "/usr/lib/python2.5/site-packages/ecore/__init__.py", line 20, in <module>
ImportError: libeina.so.0: cannot open shared object file: No such file or directory

Any idea which package is the reason for this problem, so I might try a different version of that package.
