Interesting. Never used the --tree option.

I get this:

+-biopp:astyle
  +-projects/biopp
  | +-build/biopp/src/bio_molecular/bio_molecular.cpp
  | +-build/biopp/src/bio_molecular/triplets.cpp
  | +-build/biopp/src/rna_structure/rna_structure.cpp
  | +-build/biopp/biopp/biopp.h
  | +-projects/biopp/SConscript
  | +-projects/biopp/bio_molecular.H
  | +-projects/biopp/bio_molecular.h
  | +-projects/biopp/bio_molecular.hh
  | +-projects/biopp/bio_molecular.hpp
  | +-projects/biopp/bio_molecular.hxx
  | +-projects/biopp/biopp
  | | +-projects/biopp/biopp/bio_alphabets_test.H
..... Long list follows

I grepped for *hxx* and it's only present in the qt4 tool, disabling it
does in fact makes the error code go away and prints a cleaned tree.
I would like to keep using the tool and to know what would be triggering
this behavior.
Any Idea?
