I have a similar problem (like Lingie's), right down to "-evas". Canola2 will not load -- it says it's loading but then nothing happens -- and I can't uninstall it either. When I try to uninstall, the Application Manager won't let me because of the following two files ("needed for other applications ..."): libecore0-evas and libedje0.

I posted my issue here (though I'm not sure how things proceed there): http://tinyurl.com/2lexy5
