You're right.  I got distracted by the comparison still being done between
last_size and remaining.

Can you try removing the "if(pinfo->tcp_tree != NULL)" check?

    if(pinfo->tcp_tree != NULL) {
        tcp_dissect_pdus(tvb, pinfo, tree, TRUE, 4, get_message_tcpmessage_len, 
                         dissect_message_tcpmessage);
    }

If that helps, then you should look into structuring your code like the dns
dissector does, with separate dissect_message_tcp() and dissect_message_udp()
functions.

If that doesn't help, then you might try compiling your code against the latest
development trunk as I believe there have been some changes made recently
concerning reassembly that might help you.
