Interop problem with old dropbear and new openssh

I have a router running an old version of OpenWRT with an old version of
dropbear (Dropbear sshd v0.44test3). It has been working for many years and I
ssh in from my desktop systems (running Debian Testing) with no problem.
However, recently I upgraded one of my desktops and I can no longer connect to
the router. Dropbear on the router is exiting with:
exit before auth: bad buf_getwriteptr
The desktop is running "SSH-2.0-OpenSSH_5.9p1 Debian-1" (it failed with 5.8 as
well). However, another desktop still running "SSH-2.0-OpenSSH_5.5p1
Debian-6" still works fine. The config files are identical.
I realise this is a very old version of dropbear and that you are not
responsible for changes in OpenSSH but I thought I would ask here in case
anyone else has seen this and can maybe suggest a config change to workround
