[Python-projects] hgview gives ValueError: list.remove(x): x not in list when clicking on certain changesets

[Hunter Blanks]

Dear hgview folks,

First, thanks to everyone who's worked on hgview! I think it's a great
improvement on the old tk tool.

I came across a funny bug while viewing my repository, and since I
wasn't too sure how best to ticket it, I'm passing the traceback and
some of the diff your way.  Basically, hgview fails to show the diff and
files changed for a pretty simple changeset I have.  (hgk, however,
works) In this particular changeset, I had done ``hg cp`` to copy one
file to another place, and also made a tiny change to another existing
file.

Anyway, here's the traceback:

    Traceback (most recent call last):
      File "/usr/lib/python2.5/site-packages/hgview/gtk/hgview_gtk.py", line 652, in selection_changed
        diffmsg, buff, changes = self.repo.diff(self.repo.parents(node), node, rnode.files)
      File "/usr/lib/python2.5/site-packages/hgview/hgrepo.py", line 250, in diff
        files.remove(m[0])
    ValueError: list.remove(x): x not in list

and a diff (some company code -- in Ruby, alas -- has been removed):

    diff -r 61bcdd922267 -r ff0431760ac1 app/views/assessments/show_confirm.html.erb

Naturally, when I first got this error using the Debian package (thanks for
that, too!), I cloned the hgview repository and tried it, but I got the same
error there.

I'm sorry not to debug this myself (the deadlines at my work never seem
to end) but am happy to provide any further information.  I can write
again I succeed in reproducing it elsewhere.

Best wishes,

Hunter Blanks
