            Bug ID: 4902
           Summary: test-shelve crash with general delta on
           Product: Mercurial
           Version: default branch
          Hardware: PC
                OS: Linux
            Status: UNCONFIRMED
          Severity: feature
          Priority: wish
         Component: shelve
          Assignee: bugzilla@selenic.com
          Reporter: pierre-yves.david@ens-lyon.org
                CC: mercurial-devel@selenic.com

Running test with general delta enabled by default show `test-shelve``
crashing. This highlight that our test coverage of bundle2 is too light.
