Testcase is:
$ (export OPAMROOT=/tmp/opamroot; rm -rf $OPAMROOT; opam init && opam install ocamlfind && opam install lwt)

This works with 1.1.1-1.

Fails with 1.1.1-1+b1 trying to install ocamlfind again (it is already installed by first opam install command):
[...]
# Makefile:150: depend: No such file or directory
# ocamlfind: Package bytes is already installed
#  - (file /tmp/opamroot/system/lib/bytes/META already exists)
# make[1]: *** [install] Error 2
# make: *** [install] Error 2
