[Marc Bastian Heinrichs]

Hi Jochen,

> I am using TYOP3 4.4.5 and a trunk version (around beta3) of extbase
> /fluid.

from the changelog:
-------------
Changes for 1.3.0 Beta 2a:
==========================
included in TYPO3 4.5.0 Beta 2.

This release includes a whole bunch of bugfixes and refactorings, the
most important ones listed below.
Because the FlashMessages now use t3lib_FlashMessage, TYPO3 4.5 is
MANDATORY!
-------------

Here is the commit that fixes the FE FlashMessage bug in v4.5 core
