I have a similar issue - but it is in my relatively outdated git-clone,
which I have not been able to update, since the git change was made (yes, I
know, I am not happy, but I do not have time either).

A fatal error has occurredUndefined class constant 'ALPHACHANNEL_REMOVE'in
../imp/lib/Mime/Viewer/Pdf.php:136

1. Horde_ErrorHandler::catchFatalError()

DetailsThe full error message is logged in Horde's log file, and is shown
below only to administrators. Non-administrative users will not see error
details.

ErrorException Object

    [message:protected] => Undefined class constant 'ALPHACHANNEL_REMOVE'

                        (
                        )

                )

        )

    [previous:Exception:private] =>
    [severity:protected] => 1
    [logged] => 1

)

It is not there in the production version I am using (older than the GIT
version, so something was introduced...)
