This is a follow up from Bug 36511 - SVG import: Transparent gradients shown as black non-transparent area On that bug report there are two attachments, one screen shot showing the same SVG rendered on Writer and Inkscape https://bugs.freedesktop.org/attachment.cgi?id=45971 and the SVG itself https://bugs.freedesktop.org/attachment.cgi?id=45972 As commented on Bug 36511, the shadow problem is handled there so this Bug is about the border inserted by LibO around some gradients on the penguin head and not present on the original image.
[Reproducible] with "LibreOffice 3.4Beta2 – WIN7 Home Premium (64bit) German UI [DEV300m103 (Build:1)]". I see this as a DRAW problem
