The fix to #011313 seems to have caused massive breakage on two of our 3.8 sites when I upgraded the 3.8 code to the latest svn today:

Fatal error: Cannot instantiate non-existent class: ezcontentclassnamelist in /eb/apps/ez/3.8/kernel/classes/ezcontentclassattribute.php on line 51
Fatal error: eZ publish did not finish its request

The execution of eZ publish was abruptly ended, the debug output is present below.

I commented out the entire fix to #011313 in ezcontentclassattribute.php and the sites worked again.

Strangely, not all the 3.8 sites running from this code base seemed to be affected, although I was concentrating on reverting the problem and getting the sites back online rather than pinpointing the exact criteria to produce the problem.

Thanks
