I got different error message: nxx@nxx-desktop:~$ wine winecfg wine: Unhandled page fault on write access to 0x00452000 at address 0x7bc467c1 (thread 001c), starting debugger... wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart. nxx@nxx-desktop:~$ wine notepad wine: Unhandled page fault on write access to 0x00452000 at address 0x7bc467c1 (thread 001b), starting debugger... wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart. But deleting system.reg helped indeed. Though Counter-Strike now does not work and crashes on connection to server. In Wine 1.1.11 all worked well.
