+Create a repo such that the changelog entry refers to a null manifest node:
+
+  $ hg init a
+  $ cd a
+  $ hg log
+  $ touch x
+  $ hg add x
+  $ hg commit -m "init"
+  $ hg rm x
+  $ hg commit -q --amend
+
+  $ wc -c < .hg/store/00manifest.i
+  0
+
+Make sure that the manifest can be read (and is empty):
+
+  $ hg --config rhg.on-unsupported=abort files -r .
+  [1]
+
+Test a null changelog rev, too:
+
+  $ hg --config rhg.on-unsupported=abort files -r 0000000000000000000000000000000000000000
