LO doesn't start after upgrade to 3.5.7

[Piotr Kubaj]

I've upgraded from 3.5.6 to 3.5.7. On 3.5.6 everything worked great, now
it just loads and crash. The system is a recent 10.0 built with clang
and libc++ (I know lots of people say it doesn't work with clang-built
world, but for me it did). For example, my other PC runs 9.1-PRERELEASE
built with clang (but not libc++) and LO upgraded flawlessly (and works).
