Could you check if the crash is caused by touchpad multitouch gestures or by alt+tab too?
I don't think it is being caused by multitouch trackpad gestures. TWin is the window manager from Trinity Desktop, a fork of KDE3 3.5 and it doesn't support trackpad gestures for that, or if it does, I don't use it. I used keyboard shortcuts to change to another virtual desktop there. So yeah, can confirm it happens without gestures. I don't know if it has anything to do with how the window is in another state when in a different virtual desktop but if it is in the same, doesn't happen.
Correction. It IS being caused by touchpad gestures. TWin is no longer an example of the bug in question. I also just opened an issue on KDE Bugzilla because I don't think it would be feasible to fix this but on Wine side if it is being caused by something on KWin side
