Seems to be related to reading older format data.

Here's the complete fcl file:
$ cat copy.fcl
process_name: Copy

source: {
module_type: RootInput
maxEvents: 10 # Number of events to create
}

physics: {

#define the output stream, there could be more than one if using filters 
 stream1:  [ out1 ]
 #end_paths is a keyword and contains the paths that do not modify the art::Event, 
 #ie analyzers and output streams.  these all run simultaneously
 end_paths:     [ stream1 ]  
}

outputs: {
out1: {
module_type: RootOutput
fileName: "merged.root"
compressionLevel: 1
}
}
