Incorrect SVN revision of the open file in the window title

When I open files from my project which is managed with SVN, the main QtCreator window title contains the currently open file name and what should be its SVN revision. However, the revision is incorrect. For example, it shows "helpers.h [r58929]", but 'svn info helpers.h' shows "Revision: 77841" and "Last Changed Rev: 77841". The same is shown when I run 'svn info' in trunk.

The 58929 revision is displayed when I run 'svn info' for the local SVN tree root ("Revision: 58929", "Last Changed Rev: 58924"). However, I rarely update the whole SVN tree as it includes branches and tags. The project itself is in trunk (i.e. below the root directory), and helpers.h is further below trunk.

The window title is supposed to display the file revision, otherwise it's very confusing.
