Sorry for the noise, probably I missed something, like you are using another box for building packages?
BTW, sse2_blt is nothing else but a 2D variant of memcpy. It is a rather lightweight function, which does no special sanity checking for the input arguments and expects the caller to always use it correctly. Segfaulting in sse2_blt and blaming pixman is very similar to segfaulting in memcpy and blaming glibc.

This won't be fixed ever for 2.4 webkit, please verify if this is still valid with a browser using webkit-gtk:4 slot, try with 2.10.x versions
