Browsing empty hg repo results in error

[thatch]

I assume this is the right place to enter this ticket, as the ​th:TracMercurialPlugin doesn't host any of the code.

I am running trac from trunk and the Mercurial plugin from svn at ​http://svn.edgewall.com/repos/trac/sandbox/mercurial-plugin-0.11 installed as a systemwide egg. I did not previously have the mercurial plugin for Trac installed, so I am sure it is clean.

I ran

hg init /var/hg/demo2

and the relevant portions of trac.ini are:

[trac]
repository_dir = /var/hg/demo2
repository_type = hg

[components]
tracext.hg.* = enabled

I get the following error visiting /browser on this new instance, which has no revisions:

Internal Error
unknown revision '-1:000000000000'

There is no traceback, and nothing interesting in the log with level set to DEBUG.

After making at least one revision-thingy, it behaves as expected.

Should be fixed by r4465.

I also tried to see how we could more explicitly inform the user that the repository is empty, but found no easy way. I hope it's ok like that (i.e. showing an empty listing).

Forgot to close the issue after r4465.
