Class 'tx_kesearch_lib' not found after flushing system caches
Sometimes, but unfortunatly not everytime, after flushing system caches (can be activated in installtool with [SYS][clearCacheSystem]) in the FE the following exception is thrown:
PHP Fatal error: Class 'tx_kesearch_lib' not found in /path/to/typo3/typo3conf/ext/ke_search/pi1/class.tx_kesearch_pi1.php on line 32
Then it only helps to remove typo3temp/Cache/Code and typo3temp/Data.

I installed the new version and I couldn't reproduce the error, but this time after clearing the system cache the error was caused by a different class:
PHP Fatal error: Class 'tx_realurl_apiwrapper' not found in /path/to/typo3/typo3conf/ext/realurl/class.tx_realurl.php on line 177
I think the class causing the error is random. So, it is not a bug in ke_search or realurl but in the core. Take a look at these bug-reports https://forge.typo3.org/issues/67246 and https://forge.typo3.org/issues/67366.
