/usr/bin/cg-log: line 361: echo: write error: Broken pipe

Hi,

I'm using git version 1.5.2.1 and cogito-0.18.1.
Running cg-log gives a different list of logs than running git log.
After quitting cg-log the following error appears:
/usr/bin/cg-log: line 361: echo: write error: Broken pipe.

The lists are:

cg-log:

On the previous commit (dd41b67c15eccaf3e8b0db84bdd67f37cee67d3d)
cg-log didn't show that one as first commit but the one before 
(68ba6cbe612f302aab41aab9ac224cce815d0449).
While cg-status showed dd41b67c15eccaf3e8b0db84bdd67f37cee67d3d.

Is this due to the merge?

Best regards,
Michael
