[imp] weird error

[Travis Read]

When I log into imp for the first time I'm getting the following error
below the login box. Running CVS of horde/imp/turba


Warning: (null)() [ref.outcontrol]: output handler 'ob_gzhandler' cannot
be used twice in Unknown on line 0

The error is only a warning and doens't cause me any issues but it is very
annoying...

What am I missing?

Kind regards,
