It always crash when I run wine iexplore www.winehq.org. I have tried to remove ~/.wine Then, I remove .xinitrc, run xinit, run wine iexplore www.winehq.org, everything is fine. Does the wine have a dependency on KDE? Where to paste the debug logs? WINEDEBUG=+relay,+seh,+tid wine iexplore www.winehq.org &>winebug.log The log seems increase for ever. So I kill the command. Although the log is 51M.
