yes. See
http://patch-tracker.debian.org/package/xorg-server/2:1.12.3-1
for details

Never happened for me while switching VT. although I do not do that regularly... ok -- switched to VT 1 and back (Ctrl-Alt-1 and then randomly Alt-left/right till reaching X) quite a few times (around 10) -- no problem. With suspend I think I would have experienced it by then. Also, may be of relevance:

if X crashes during suspend and I end up again at the kdm login prompt -- I would still have my 'half-moon' light blinking until I switch to e.g. VT 1 -- then it would finally suspend.

happened originally with KDE4 + awesome... now it is XFCE + awesome -- the same story

my ~/.xsession has

    awesome &
    sleep 3
    xfce4-session

It is reproducible on around 5-10th occasion on random -- never yet tried to cause it on purpose -- I thought to give it excessive troubleshooting one day... if I get a moment I will run it through valgrind... although if it is some kind of a race condition between threads, it might not get triggered
