+Subject: [PATCH 01/24] Bug 668587 - Double free() for some SVG rendering
+
+The fix for bug 665648 introduced a memory corruption.
+Now the #if-0'ed code as well as the #else branch respect
+DiaSvgRender::get_fill_style() having a const return.
+(cherry picked from commit 47bb76af3ba20b5e83be79a874df02c405934899)
