Number of processed events is not always correct for empty samples
I run over some files which are empty. This is the output I get during analysis.py:
+ user.brottler.13790388._000038.CxAOD [ .... ]
INFO in BBTauTauObjectSelectionAlgorithm::initializeSingleton(...) : This sample seems to be empty!
+ user.brottler.13790388._000038.CxAOD [ OK ] 5'082 1.71
However, the final summary states
INFO: finished cutbased analysis run over 0 events in 1 samples after 1.77s (0.0 Hz)
which is correct.
