you marked this thread as solved (green icon upper-left corner) !? Is it actually solved?
---
The log-entry provided is a small glitch introduced by eZPublish 4.3 and/or 4.4 but does not really lead to an fatal error you mentioned above. My first guess is a incomplete checkout, unmet requirements, false/wrong/missing permissions on files or directory's, ... something.
Can you give more details about your setup?
Also take a look into php errorlog which is the syslog when on linux and if enabled in php.ini.
