Not sure where the proposed patch is the correct fix - to me it seems that the bug is in the rendering code (else Inkscape 0.49 will render old files considerably different than current stable 0.48.4, and also different than e.g. web browsers):
Please open attached sample file (created with Inkscape 0.48.4) first in stable Inkscape 0.48.4:
- all three objects have the same shade of grey
Now open the same file in current trunk (unpatched, or with Jabiertxo's patch applied - doesn't matter):
- the blurred object with a preserved transformation (a flipped clone of the blurred original) renders with a noticeably darker shade of grey.
