load & store this attachment: http://bugs.documentfoundation.org/attachment.cgi?id=164196 load it again, the shape is distorted, all curves became straight lines. very recent regression, i see it sill working in build of commit 217122387f6e0ef657b8ba85eae082b448901cec from Aug. 25.
oops, i was confused as to what build shows the bug, it's actually *older* than the one from Aug. 25, it's from commit 32090b018d9ff81659a4c9ed41c64109ebebe4fc (Aug. 3) so it's fixed already :)
