[Oliver Hader]

The following changes were committed to SVN Trunk (rev. 6055)

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=12064

Branch: Trunk

Problem:
When editing on forms in the backend, the following warning appears:
Warning: in_array() [function.in-array]: Wrong datatype for second
argument in /[...]/typo3/trunk/t3lib/class.t3lib_tceforms.php line 3769

Solution:
Check whether the accordant key is really an array.

Notes:
This bug was discovered while testing the new error- and exception
handling (RFC #9355).
