This bug is really weird. I've installed native GDI+ and comctl32 libraries and
now backtrace looks this way:

fixme:ieframe:PersistStorage_InitNew (0x154160)->(0x7edafebc)
Unhandled exception: page fault on write access to 0x00000000 in 32-bit code
(0xb75b4e93).

I'm removing hhctrl.ocx as a faulty component because I've no idea what is
crashing here.
