Summary: BZFlag client can get stuck when using spin on group

Initial Comment:
Some clients like mine
(2.0.5.20051028-DEVEL-darwin8.2.0-SDL) get stuck on
certain occasions where others don't. Note that I am
not refering to the usual cutting edge problems, rather
a bug that have been in older "STABLE"-tagged versions,
too.

The provided sample map will make my client stuck
without displaying "sealed". Jumping doesn't work, I
can't even hear the jumping sound on that box in the
sample map. Observers have described me being jittering
vertically what I have been able to see at another
player both as observer and as player being near their
position.
Not all players are affected by this bug, the majority
of players are not getting stuck on the sample map.

I have run the sample map and connected with the client
version listed above with parameters -d -d -d -d and
got pasted the output to
http://bzflag.pastebin.ca/27174 in case it helps.
Note that replacing "spin -90 0 0 1" with "spin 270 0 0
1" fixes the problem for me and I was stuck when trying
to pause and was unable to move between both tries.

With WG the behaviour changes a little bit in a way I
am unable to describe exactly but you can move with
that flag when being on the box.

My impression is that the tank never really hits the
box but does much low jumps before touching it and get
stuck this way as you can't move in the air without WG.

I am using Mac OS X version 10.4.2 and I have seen one
linux player with SDL that got stuck, too.
