Created attachment 487733 [details] .xsession-errors before attempting Alt-F6 Description of problem: When switching between windows of a single app (default keybinding: Alt+F6), Gnome Shell would immediately crash. The first crash just causes it to respawn; if a second attempt is made within a short time, gnome-session refuses to respawn it and shows the Fail screen with a button to log out. This only happens after today's update. I verified it on two computers -- after it occurs on the first (ATI Radeon 5650) I checked on a second (Intel Arrandale) that has not been updated; Alt+F6 works there until I updated. Note: Alt-Tab works perfectly fine. No other visual glitch detected apart from the known crash when switching background wallpaper. Version-Release number of selected component (if applicable): gnome-shell-2.91.92-3.fc15.x86_64 gnome-desktop3-2.91.93-1.fc15.x86_64 gnome-session-2.91.93-1.fc15.x86_64 How reproducible: Always Steps to Reproduce: 1. Start two windows of, e.g. gnome-terminal 2. Alt-F6 3. Alt-F6 again Actual results: First Alt-F6 respawns gnome-shell. Second invocation causes gnome-session to refuse to continue spawning Expected results: Should cycle between the two terminal windows Additional info:
