I have found the problem, not patch on patch, but a control does not exist in the dialog, when find in files.
It makes no sense to adjust the selection when doing find in files, because the search job is a one shot. A similar change should happen as the fix I did yesterday for the "wrapping". just return false in that case.
[EDIT] : just saw you came to the same conclusion and already committed (svn wanted me to update before I could commit ;-) ) --> so fixed
