Hello release team, Mercurial's hgk extension fails to start if the configuration files of another extension are still present after a package removal.
This is bug #513183 - hgk fails to start when hg emits warnings.
This happens under relatively common conditions (package of an extension
is removed, but not purged).
The hgk extension provides the command "hg view" which is an equivalent of
gitk in mercurial world. Since I know how important gitk is for me I thought
I should try to fix the problem for mercurial.
I provided a workaround and prepared an NMU which should have made the
problem go away with a simple upload[*] and approval from the release team.
The interdiff, the dsc , the .changes file and the new diff.gz are attached.
Changelog is:
mercurial (1.0.1-5.2) testing-proposed-updates; urgency=low
.
* Non-maintainer upload.
* added a workaround for the crash of hgk when hg was emitting
warnings (Closes: #513183)
Since, as I can see, the maintainer of mercurial hasn't acted at all
since I provided
the patch and NMU,
I am requesting pre-aproval and a sponsor for mercurial/1.0.1-5.2.
The detailed description of the problem and the way I worked around it
is described at:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513183#67
For your convenience, is reproduced here (unimportant bits removed):

> realising I was fighting someone else's battle and in the end I
> settled for a (quite) elegant workaround.

> To avoid hgk's crash because of warnings, we print warnings

> In order to preserve user's possible preference for another hg

> call that HG, not the system hg, if HG was initally set.
[*] I mistekenly forgot to set the distribution to "testing-proposed-updates"
instead of "unstable" in the files in the NMU proposal, but I built on
lenny, so that is minor edit which is fixed now in the attachments.
