Changes in subversion are not correctly attached to submodules in multi module
projects. This only works in the root module.

This is due to the fact that the changelog is build with name of submodule as
prefix and the changes from svn contain the complete path within the repository.
In the normale layout the always is /trunk. Because of this a svn change will
never start with the prefix of the submodule. The prefix for the root module is
empty therefor this will work.
One idea to fix this is to remove the end of the svn url from beginning of the
svn change

svn url:
https://host:port/svnrepo/path
change path
/path/submodule/src
change path after remove of the prefix
/submodule/src

This bug also breaks the email notification for maven projects.
