I have this issue on two computers, both upgraded from 12.04 to 12.10. I've mostly given up hope on ever running webapps at all but recently I discovered some new stuff.
1) Creating an syslink in /usr/local/share/ to /usr/share/unity-webapps/ seems to work. This is even after purging a all possible packages that are related to webapps!
Even after doing this I still can't run any webapps but the Twitter webapps keep showing up, even after I removed the package. My guess is that somehow older configuration stuff from the PPA is still on my system and is looking at the older files.
