I can confirm the very same thing : 1.1.33 worked fine, but 1.1.34 crashes on game startup. Downgrading solves the problem. In the Runes of Magic directory, the game created a crash report, consisting, among other things, in an XML file that gives more details : ExceptionRecord ModuleName="D:\RunesOfMagic\Client.exe" ExceptionCode="0xc0000005" ExceptionDescription="EXCEPTION_ACCESS_VIOLATION" ExceptionAddress="0x7e1e14de" By reading it, i guess it happened in : /usr/local/bin/../lib/wine/riched20.dll.so There is also a dump file.
