[issue1285] hg glog Mercurial crash

[Guido Ostkamp]

New submission from Guido Ostkamp <hg at ostkamp.fastmail.fm>:

hg glog crashes Mercurial, if executed outside of repo. This might be no
standard usecase, but still Mercurial should not crash.

Tested with Crew repo, version a04d8cadb6af.

hg init repo
cd repo
echo "line" > file
hg add file
hg commit -m "initial checkin"
cd ..
hg glog repo
** unknown exception encountered, details follow
** report bug details to http://www.selenic.com/mercurial/bts

** Mercurial Distributed SCM (version a04d8cadb6af)
