Bridge over Multilink no passing packets bigger than 1458 bytes

I have configured a IRB bridge over multilink on routers 2801 using a Multilink with two E1 links, I can do ping from each side to the other, but when I try to put traffic over 1458 bytes I get TIME OUT, same problem when I try to pass files usin FTP.

Cisco IOS Software, 2801 Software (C2801-ADVSECURITYK9-M), Version 12.4(1a), RELEASE SOFTWARE (fc2)

Port 3 (FastEthernet0/0) of bridge group 1 is forwarding
   Port 10 (Multilink1) of bridge group 1 is forwarding

I do not know if Bridge over multilink was ever offically supported over multilink, even if configurable.

The TAC may have a word on this perhaps.

Thanks Paolo for the advice,  I have worked the bridge configuration with no luck, when I just live one of the interfaces in the bundle I have no problems, but when I put the two serial interface in the bundle the problem appears, I think you right, but I would like to get an official answer from CISCO.
