I've managed to reproduce the crash and hang, running svn r1949. I'll build
a HEAD svn later on and try to see if it appears there as well.
r=/mats/svn/repos3
svnadmin create $r
svn mkdir file://$r/trunk -m "rev 1"
svn co file://$r/trunk -d x
cd x
echo bar > bar
svn add bar
svn ci -m "rev 2"
svn mkdir file://$r/tags -m "rev 3"
# if these two lines are commented out, then the rest works
svn cp file://$r/trunk file://$r/tags/t1 -m "rev 4"
svn rm file://$r/tags/t1 -m "rev 5"
# crash
svn cp file://$r/trunk -r 3 file://$r/tags/t1 -m "crashes"
# hang
echo foo > foo
svn add foo
svn ci -m "hangs forever"
