Missing regeneration of index files

[saarnold]

Currently when replaying logs, containing already existing index files, errors like this occur:

/tools/pocolog/lib/pocolog/file.rb:745:in `data_header': payload was supposed to be  bytes, but found 1422563323 (RuntimeError)

After the last update of the stream aligner #6 it seems necessary to recreate existing index files. This is not triggered automatically.

Complete backtrace, please.

And ideally a log file / index file combination which triggers the problem ...

As soon one does a right click on the RBS output port the error occurs.
