Comment:

 There is something weird in my commit and I don't understand why.
 I have not modified the `generic_graph.py` file but the commit contains
 code from it O_o
 I'm sure I have created this branch starting from the `develop` branch
 (after a git trac checkout develop; git trac pull; git branch ifub; git
 checkout ifub; fix ifub problems and do test and docbuild; git commit...;
 git trac push 17873).
 Any idea on how to resolve this?

 David.
