Our user is receiving the following error when accessing any of the areas under the Horde Calendar:

Fatal error: Call to a member function on a non-object in /usr/local/cpanel/base/horde/kronolith/lib/Driver/sql.php on line 291

I have tried a forced update of cPanel/horde, but this error appears to be in the latest version. There is a similar error that is documented with the horde developers, but I have not seen any recommendations for this error specifically. Does any one have a fix/workaround?
