How can I get Mercurial to push commits again?

I'm not aware that I changed anything and am running Ubuntu 10.10. Mercurial had been working fine and then all of a sudden when I started pushing commits this morning I started receiving the following error: ``` ** unknown exception encountered, details follow ** report bug details to http://mercurial.selenic.com/bts/ ** or mercurial@selenic.com ** Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39) [GCC 4.4.5] ** Mercurial Distributed SCM (version 1.6.3) ** Extensions loaded: convert Traceback (most recent call last): File "/usr/bin/hg", line 27, in <module> mercurial.dispatch.run() File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 16, in run sys.exit(dispatch(sys.argv[1:])) File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 34, in dispatch return _runcatch(u, args) File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 54, in _runcatch return _dispatch(ui, args) File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 494, in _dispatch cmdpats, cmdoptions) File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 355, in runcommand ret = _runcommand(ui, options, cmd, d) File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 545, in _runcommand return checkargs() File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 499, in checkargs return cmdfunc() File "/usr/lib/pymodules/python2.6/mercurial/dispatch.py", line 492, in <lambda> d = lambda: util.checksignature(func)(ui, *args, **cmdoptions) File "/usr/lib/pymodules/python2.6/mercurial/util.py", line 420, in check return func(*args, **kwargs) File "/usr/lib/pymodules/python2.6/mercurial/commands.py", line 2855, in push newbranch=opts.get('new_branch')) File "/usr/lib/pymodules/python2.6/mercurial/localrepo.py", line 1227, in push return self.push_unbundle(remote, force, revs, newbranch) File "/usr/lib/pymodules/python2.6/mercurial/localrepo.py", line 1263, in push_unbundle return remote.unbundle(cg, remote_heads, 'push') File "/usr/lib/pymodules/python2.6/mercurial/httprepo.py", line 236, in unbundle tempname = changegroup.writebundle(cg, None, type) File "/usr/lib/pymodules/python2.6/mercurial/changegroup.py", line 106, in writebundle for chunk in chunkiter(cg): File "/usr/lib/pymodules/python2.6/mercurial/changegroup.py", line 31, in chunkiter c = getchunk(source) File "/usr/lib/pymodules/python2.6/mercurial/changegroup.py", line 14, in getchunk d = source.read(4) File "/usr/lib/pymodules/python2.6/mercurial/util.py", line 924, in read for chunk in self.iter: File "/usr/lib/pymodules/python2.6/mercurial/localrepo.py", line 1613, in gengroup for chnk in filerevlog.group(nodeiter, lookup): File "/usr/lib/pymodules/python2.6/mercurial/revlog.py", line 1196, in group d = self.revdiff(a, b) File "/usr/lib/pymodules/python2.6/mercurial/revlog.py", line 1005, in revdiff return self._chunk(rev2) File "/usr/lib/pymodules/python2.6/mercurial/revlog.py", line 997, in _chunk return decompress(self._chunkraw(rev, rev)) File "/usr/lib/pymodules/python2.6/mercurial/revlog.py", line 112, in decompress return _decompress(bin) zlib.error: Error -5 while decompressing data: incomplete or truncated stream ``` I tried to Google parts of it, but I couldn't find anything relevant. Any ideas? Thanks for looking. :)
