Hello,

I'm using the following:

[campedel@betelgeuse ~]$ git --version
git version 0.99.9g
[campedel@betelgeuse ~]$ cg --version
cogito-0.16rc1

I think there's a bug in gitk diffing, both
	'Diff selected -> this'
and
	'Diff this -> selected'
fail when applied on the result of a merge.

To replicate the problem you can use the attached script
and then try diffing against branch_1 head.

Thanks for your attention (and for your wonderful work!)

Lorenzo


cg init
echo abc > a.file
cg add a.file
cg commit -m 'added a.file'
cg tag tag_1
echo def >> a.file
cg commit -m 'modified a.file'
git checkout -b branch_1 tag_1
echo ghi > b.file
cg add b.file
cg commit -m 'added b.file'
cg merge -c master
cg commit -m 'merged with master'
gitk --all

exit

```
