SDK 1.1 RC QtCreator crashes when you try to open Options menu on X86_64

Install Qt_SDK_Lin64_offline_v1_1_rc_en.run, put x on remove old settings (and I've removed old beta sdk with rm rf). Everything installs fine. Start QtCreator, choose Tools>Options -> crash.

Doing the same with: "strace qtcreator" gives:
