TYPO3 Core

There have been issues with the RTE in combination with EXT:solr. Solr reads TypoScript in the backend by instanciating TSFE. The RTE tries to detect whether it's running in FE mode / context. Due to the existing instance of TSFE the RTE then believes it's in FE mode and tries to load and merge language labels. This then leads to a fatal error as t3lib_div::array_merge_recursive_overrule() tries to merge an array with NULL.

The issue is easy to fix by properly detecting the FE context:

TYPO3_MODE == 'FE'

Described here:
http://forge.typo3.org/issues/9375
http://forge.typo3.org/issues/9983

I was able to reproduce this behavior. You would need the early access version though.
