[TYPO3] no backend module can be started in TYPO3 SVN trunk

[Franz Holzinger]

Hello,

with the current SVN trunk I cannot get any backend module started
again. Only the clearing of caches works.

With Firebug I get the error message:
-------------------
top.topmenuFrame.goToModule is not a function
[Break on this error] top.topmenuFrame.goToModule(modName, cMR_flag,
addGetVars);
-------------------

The same error message on Windows with Internet Explorer 6.

Can anyone confirm this is a bug? Or what did I do wrong with the
installation? (It works fine with all other TYPO3 versions on all
browsers and servers.)
Thanks for any hints how can make it working.

Greets,

Franz
