 I have accidentally set EITCrawIdleStart to 1.
 This discovers a segfault with back to back recordings.
 The backend crash if it the active eit scanner thread starts direct after
 the first recording and call  QMutexLocker lock(&stateChangeLock) from the
 TVRec::SetChannel function.
 I don't know about QMutexLocker, so I don't now why it crashes when it try
 to lock.
 Maybe a simple solution where to prevent setting the EITCrawIdleStart
 value to a low value.
 I think the first crashes came with the multirec merge.
 The backtrace is from svn 16501.
