[TYPO3-dev] Problem with Creating new pages with specific doktype

[Sebastian Gebhard]

I have a section in my page tree where only SysFolders are allowed.

Therefore i wrote into TSconfig:
TCEFORM.pages{
   doktype.removeItems = 1,6,4,7,3,255,199
}
So that only 254 (SysFolder) is left.

When I create a new Page using "The Wizard" it fully works and the new 
page is a SysFolder at once.
When I just use the "New record" function, doktype=1 is preselected so 
that the dropdown says [INVALID VALUE ("1")]

What can I do to fix that? Is that a bug?
