The same problem occurs between Debian versions 3.2.6 and 3.6, and now  
with debian's 3.8.1 (not yet tested with the latest patches).

First sync with a brand new backend does not trigger the error.

But once the error is here, even after removing the mailbox from the  
destination backend, the error still occurs, whith a segfault on the  
3.2 backend.

It seems the error occurs when some big folders on big malboxes are  
moved arround.

I have not found any way to fix the mailbox, but once it is  
transferred to another 3.2 backend server, the sync on the new 3.6  
completes successfully and the initial backend can finish o sync his  
other malboxes.

Sincerly,
