I also have the same problem except mine installed successfully but then it would load and load and then nothing happens. So, I tried the test that was suggested and this is what I got. I tried to Un-install Canola2 to re-install but it refuses to uninstall because it tells me that: "Required by application packages and lists 2 files:

libecore0.evas (0.9.9.04-maemo.7)
libedje0 (o.5.0.042-maemo1)

Anyway, here the result of the terminal test:

~ $ canola -vvvv
Traceback (most recent call last):
File "/usr/bin/canola", line 141, in <module>
setup_dot_canola()
File "/usr/bin/canola", line 125, in setup_dot_canola
check_prefs(prefs_path)
File "/usr/bin/canola", line 99, in check_prefs
canola_prefs = PluginPrefs("settings")
File "/plugin_prefs.py", line 32, in __init__
File "/plugin_prefs.py", line 41, in _load
EOFError
~ $

What shall I do? Please help.
