[TYPO3-english] Pagetree missing after upgrade to 4.5beta3

[Žiga Dolhar]

Hello list,

I upgraded my 4.5beta2 installation to beta3.

The pagetree seems to be missing in some backend modules.

It is missing in the following modules:
- View
- List
- Versioning
- Template
- Recycler

It is present in the following modules:
- Page [from tv module]
- Templavoila
- Newsadmin [tt_news module], Newssortierung [another extension]

I have cleaned my cache (typo3temp and browser) and tried copying the 
4.5beta3 source zip package again, to no avail.

Before reporting a bug on bugs.typo3.org - is anyone else experiencing 
this issue?
