Hello,

I am experiencing the same issue on a Debian 7 system.

It seems like XCache is broken on CLI in the version that Debian 7 uses
(2.0.0-4). My settings used for Apache and CGI are identical and similar to
yours, but phpinfo() shows that the opcode and variable caches are disabled
when executed via CLI, while both appear enabled as expected via Apache.

Related bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707057

The report suggests that Debian 8 should contain a fixed version.

My quick-and-dirty fix is to comment out the log line in Bootstrap.php.

Greetings
Tilo
