Exception due to version number

[zenker]

On a Raspberry my Application keeps crashing due to uncaught exception. The exception is thrown in UnidirectionalProcessArray<T>::writeInternal. I don't know at which point the wrong version number is assigned. It is triggered in different cases calling the write() method in ApplicationCore. Here the PeriodicTrigger caused the exception, which is bad because I would have to change the PeriodicTrigger module by introducing a try/catch block.

terminate called after throwing an instance of 'ChimeraTK::logic_error'
  what():  The version number passed to write is less than or equal to the last version number used.
terminate called recursively
ChimeraTK error catched: The version number passed to write is less than or equal to the last version number used.

There is one line saying that the error was catched. This output results from catching that error inside my application by guarding the write call:

try{
      writeAll();
} catch (ChimeraTK::logic_error &e){
      std::cerr << "ChimeraTK error catched: " << e.what() << std::endl;
}

But as I said before in the PeriodicTrigger that error is not catched.

Should be fixed with the latest version of the framework.
