I did "aptitude install php5 php5-mysql libapache2-mod-php5" which replaced the installed libapache2-mod-php5filter with libapache2-mod-php5. This fixed my problem.
As I am not sure whether this is expected behavior of php5filter or not, I assume it is as expected, and consider this bug to be closed.
