You probably have old, downloaded web addons in you addons/ folder (pad, share or wiki, most of the time). Some modules moved around between 6.0 and trunk, and not all addons were version-bumped, so they're still looking for the old module because they were not automatically overwritten.
Remove the non-versioned addons, it should fix the issue.
