Comment #6 on issue 189 by aleks.dimitrov: MultiToggle to Full and tabbed layout makes X crusn http://code.google.com/p/xmonad/issues/detail?id=189 Hello, I'm not the original author, but I just wanted to say that I ran into this issue yesterday, too. At first it manifested itself in XMonad consistently segfaulting, and when I pried a little harder, I could reproduce the OPs exact problem (I think.) The following configuration triggers it: import XMonad import XMonad.Layout.LayoutCombinators hiding ((|||)) import XMonad.Layout.MultiToggle import XMonad.Layout.MultiToggle.Instances import XMonad.Layout.Combo import XMonad.Layout.Tabbed layouts = mkToggle (NOBORDERS ?? FULL ?? EOT) $ simpleTabbed **||*** Full main = do xmonad $ defaultConfig { layoutHook = layouts } I'm using XMonad 0.9.1, Unbuntu 10.10 (using the XMonad version of the Ubuntu repo.) In my case, xmonad usually segfaults when I try to change something about the workspace's dimensions (say, mod-H or mod-L or mod-B, all of which trigger resizing of the windows.) Any way to work around this?

Thanks for the instantaneous answer! I'll get darcs and try it out. Seeing as your comment was almost a year ago, I assumed it fixed in the latest stable release. I'll report back in a moment.
