More details from Vlad (I translate his e-mail from Russian):

"This trick (with splitting revisions ranges) cannot be used because 
error occurs on the first revision. My friend long time working on 
Windows without version control, and then I (i.e. Vlad) get 1GB of data 
files and create new repository, and then push it to server. So, 
repository from the start becomes very big. And because usual checkout 
command fails, I need to push branch via SMB.

More info. In the repository there are too many big files (10MB and 
bigger). So, your assumption about big amount of requested data is 
probably true.

I have python installed and therefore can patch python-based version of 
bzr to check John Meinel's patch.

Logs will be later."
