I have the same problem here, but I think I found the cause. My recent backups made by backintime are not incremental any more, which is why they take a lot of time to perform.
I measured the size of the backups made by backintime :
du -h --max-depth=1
0 ./backintime
4,3G ./20100504-000000
26M ./20100509-000000
4,6M ./20100511-000000
4,5G ./20100514-000404
4,5G ./20100516-000000
4,7G ./20100517-000000
18G .
So I can say that may backup are not incremental any more since May 11-14.
I have changed the way to access my backup share on May 13th : before that date, I used NFS ; after that date, I use CIFS. So it seems that my backups are not incremental any more since I access my backup destination via CIFS.
