Sorry - I don't use Google Groups enough, so I just hit "Post Reply" assuming that it would be smart enough to put the reply in the right place.
I looked at the XFCE keyboard shortcuts and window manager keyboard shortcuts, and Ctrl-Alt-c/v aren't in use. There might be another place to look, but those are the main ones off the top of my head. However, I'm not sure if this is a window manager issue since the keyboard shortcut is controlled by the Qubes Clipboard program (qui-clipboard).
I don't know enough about the Qubes internals to trace how it picks up the setting from /etc/qubes/guid.conf (and why it isn't accepting my values after I changed them). I tried doing a recursive grep to find any other places where the default shortcut may be set, but it got a little mind-bending.
I'm happy to provide more details from my system, though - my fingers just really want to use my custom shortcut because they've been confused ever since I upgraded. ;-)
