I realise this is of no interest to the developer but I added some extra
logging to itemqueue.cpp to see what was happening:
--------------------------------------------------------------------------------------------------------
bool ItemQueue::processBatch()
{
  kDebug() << "pipline size: " << mItemPipeline.size() <<
mFetchedItemList.size();
  if ( mRunningJobs > 0 ) {//wait until the old graph has been saved
    kDebug() << "blocked: " << mRunningJobs;
    return false;
  }
  if ( mRunningJobs != 0 ) {
    // added by me
    kDebug() << "mRunningJobs == " << mRunningJobs << "!!!!!";
  }
  Q_ASSERT( mRunningJobs == 0 );
  mRunningJobs = 0;
--------------------------------------------------------------------------------------------------------
.xsession-errors
akonadi_nepomuk_feeder(13953) ItemQueue::processBatch: mRunningJobs ==  -1
!!!!!
ASSERT: "mRunningJobs == 0" in file
/home/lindsay/Projects/akonadi/kdepim-runtime/agents/nepomukfeeder/itemqueue.cpp,
line 116
--------------------------------------------------------------------------------------------------------

So for some reason mRunningJobs is actually -1, which I presume should never
happen.

How thread safe is this stuff? I don't see any use of thread sync primitives.
