Subject: git-rebase: "Patch is empty. Was it split wrong?"

I'm getting the above message when doing a git-rebase and wondering
is is due to user error in how I am using rebase or b/c of something
else.

My situation is that a I have a main branch "dev", against which
others have developed some branches and I merge into my local
version of dev. After merging these I want to rebase to remove the
merge itself from the history (I need to linearize the history, 
long story, don't ask why):

$ git-checkout -b f2.6.24_dev f2.6.24/dev
Branch f2.6.24_dev set up to track remote branch refs/remotes/f2.6.24/dev.
Switched to a new branch "f2.6.24_dev"
$ git-merge 27234_v01 27470_v01 27476_v01

Patch is empty.  Was it split wrong?

Am I just abusing git-rebase here or is there something wrong with my tree?

Version is 1.5.4.4.

Thanks,
