KRename 4.0.0-1, KDE 4.3.3, Arch Linux i686
A given filename to be edited in the advanced mode of KRename is not handled correctly if there are several dots or a [ or ] in it.
Several dots seem to work partly but if smaller parts of the filename are to be re-used (e.g. Pattern [$1-3][$7-16]) mostly it doesn't work correctly.
The brackets seem to be 'escaped' by the program incorrectly because the new filename often contains \] where the old one contained ].
