Checkin gives error "abort: There is no Mercurial repository here (.hg not found)!" on TortoiseHg/Windows version

[jens.lund at nordea.com]

The problem below is still present in hg 1.4/TortoiseHg ver 0.9 :-(

Summary of discussion so far in this thread:

* Running with traceback:
$ hg --traceback ci -m second
Traceback (most recent call last):
  File "mercurial\dispatch.pyo", line 46, in _runcatch
  File "mercurial\dispatch.pyo", line 441, in _dispatch
RepoError: There is no Mercurial repository here (.hg not found)
abort: There is no Mercurial repository here (.hg not found)!

* It doesn't seem to be related to anti-virus software or similar
running on the computer

* It only happens for the TortoiseHg installed version, not the cygwin
version.

* It fails both on network drives and local drives
