Status changed to 'Confirmed' because the bug affects multiple users.

This bug appears, when the x86_64 version of clang is installed. When you try to install clang-3.5:i386 some of the 64-Bit libraries get removed due to conflicts, but obviously not libclang1-3.5.

The sloution is to first completely remove clang-3.5 and especially libclang1-3.5 and then install clang-3.5:i386
