Comment #5 on issue 355 by gwern0: XMonad.Actions.WindowGo (runOrRaise) fails on the specific command "chromium" http://code.google.com/p/xmonad/issues/detail?id=355 With more sleep, I see I should've suggested you fire up GHCi and do a safeSpawn in there instead, in hopes that you would see an error message or informative output of some other kind. Is http://aur.archlinux.org/packages/chromium-browser-bin/chromium-browser-bin/... the script concerned? What happens with safeSpawn "full-path-to-actual-binary-and-not-the-script"? Or with just the actual-binary? -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
