Mail system causes a significant issue when using the Omega base theme.
Whenever I clear cache via the performance admin page it breaks the site (near WSOD except for logo/site name) which I then have fix by clearing the contents of the cache table in the database. At first I thought it was theme related but I managed to exclude that possibility by trying the theme (including subtheme) on a fresh Drupal install. I tracked this to Mail System by disabling all contribs and re-enabling them one by one. I tried reverting to Mail System 2.33 but that did not solve the issue.
I suspect Mail System somehow prevents the subtheme from using (preprocess) results from alpha, a component of the omega base theme. I confirmed that by copying a preprocess function into my subtheme's template.php. Solved the undefined rdf variable issue (but is not how the theme is designed to work).
Any ideas what may cause this?
