[imp] Killed hhorde/imp ...

[cyx]

Hi

Did a pear install -a today, resulted in a totally dead horde/imp. After
login, the only response I get is: Fatal error: Cannot override final method
Horde_Core_Notification_Handler_Decorator_Base::notify() in
/usr/local/www/horde/imp/lib/Notification/Handler/Decorator/ImapAlerts.php
on line 25 

Not even the test.php scrip responds .

Anyone with any idea, what went wrong  during the update (updates went
smooth, no error messages at all).

Regards Werner
