[kronolith] PHP Error in Syslog from Kronolith

[Helmut Schiefer]

Dear folk,

I migrate my horde3 installation to horde4. If I login to the system,  
syslog shows the following error to me.

/usr/share/php/Date/Holidays.php"]
Dec 31 11:35:23 hal2000 HORDE: [kronolith] PHP ERROR: get_class()  
expects parameter 1 to be object, array given [pid 23035 on line 365  
of "/usr/share/php/Date/Holidays.php"]

I have now glue to solve the error. Any Idea?
