Same here, after yesterday's upgrade.
While I was doing the upgrade, I got a fatal error.
Dialog said some file was not going to be overwritten because it was also contained in something else -- cannot remember the exact error.
I haven't tried fixing it yet. Doesn't really effect me, because I normally run the raw trunk release (currently Chromium 31)
Code:

You could try the trunk build (not for the faint of heart). It requires manual installation/updating.
If you're not comfortable doing that, I'll try to fix Chromium 29 later today, and post the results here.
