Bug Description

I have a wired issue with the ogre-1.8 packages. Everything works fine except when there are animated meshes then I get the folllowing crash:

"0x00007ffff790edfe in Ogre::softwareVertexSkinning_SSE_General (pSrcPos=0x7fffe15a1da0, pDestPos=0x7fffd15a2800, pSrcNorm=0x7fffe15a1dac, pDestNorm=0x7fffd15a280c, pBlendWeight=0x7fffd1562244, pBlendIndex=
    0x7ffff78e9c44 <Ogre::Mesh::softwareVertexBlend(Ogre::VertexData const*, Ogre::VertexData const*, Ogre::Matrix4 const* const*, unsigned long, bool)+1444> "H\213\274", <incomplete sequence \310>, blendMatrices=0x7fffd1562240,
    srcPosStride=140737488341168, destPosStride=24, srcNormStride=24, destNormStride=24, blendWeightStride=24, blendIndexStride=8, numWeightsPerVertex=8, numVertices=1)
    at /build/buildd/ogre-1.8-1.8.0/OgreMain/src/OgreOptimisedUtilSSE.cpp:535"

Before I was using the ogre-1.8 packages I build RC1 and linked it statically. That worked fine :/

I also reported the issue upstream: http://www.ogre3d.org/mantis/view.php?id=553

However it would be nice if somebody using Ubuntu (quantal) could test if he/she has the same problem.

To test just run the SampleBrowser and select the "Character"-Demo.
