meld diff does not work with hg

[Andrew]

Binary package hint: meld

Meld cannot diff files with mercurial / hg. Steps to reproduce:

create an hg repository
commit a file
make a difference
run 'meld .' from the directory
double click the changed file

you get an error like:

"Could not read from /home/me/hg/-r 2c9a73550084 file.xml

The error was:
[Errno 2] No such file or directory: '/home/me/hg/-r 2c9a73550084 file.xml'"

It looks as if meld is inserting the revision argument inside the path between the base directory and the file that is being diff'd.

Ubuntu: Intrepid
Meld Version: 1.1.5.1-2ubuntu2
Mercurial Version: 1.0.1-5.1

I have seen this in Hardy too, but just reporting it now

Found the bug in debian:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=428843

Which points to:
http://svn.gnome.org/viewvc/meld/trunk/vc/mercurial.py?r1=927&r2=949

A new upstream release have been uploaded to Jaunty archives. I was not able to reproduce this bug following the instructions in the bug report. Please test the new version and report if this bug still reproducible.

this problem still exists in intrepid. i did a fresh install of meld 1.1.5.1-2ubuntu2 and mercurial 1.0.1-5.1 on intrepid today via synaptic and had the same problem.

i applied the one-line patch referenced in Andrew's comment
http://svn.gnome.org/viewvc/meld/trunk/vc/mercurial.py?r1=927&r2=949
by hand, and it fixed the problem

[Michael Budde (mbudde)]

This bug should be fixed in meld 1.3.0-1 which has just been sync'd from debian.

[Andrew (andrew-rw-robinson)]

Finally verified that it is indeed fixed in Jaunty, thank you
