I've been running with this snapshot on my brand new Vista RC2 dual-boot 
for a few days, and FWIW, I haven't had any problems with it.  (With 
1.5.21, I got the above errors all the time.)
I'm not doing anything special with it, though - I'm just running a zsh 
shell in rxvt-unicode, and doing the usual shell stuff.  Oh, and I'm 
editing with gvim.
(I'm not using the Cygwin/X server, though, but running Cygwin X clients 
on an Xming server.)

After reinstalling I rebase-all'ed using the default parameters, no 
problems.

Thanks for making my Vista install bearable!  :-)
