Well one example was that from the beginning of time until the 4.3 
release, you could only specify a single USB device in the config file 
for an HVM domain.
Another one is the qemu one we're discussing right now -- it was 
reported back in February I think, but it's only recently actually 
getting the attention that it needs to be sorted out.  The root cause 
was known by March, at which point there would have been plenty of time 
for a "proper fix".
And there's random things like cd-eject or cd-insert not working in 
certain circumstances (namely, when blktap was available).  It's 
something basic, but something we don't really use very much, and never 
got flagged up.  So it was broken in the 4.2 release.
I don't really know if this is the kind of thing that users are talking 
about, but if I used a release of a (supposedly) mature product, and 
something as basic as "insert a CD" crashed, I wouldn't be very impressed.
