Dropbear: exit status of remote shell not properly returned to client

[Dr. H. Nikolaus Schaller]

Does anybody have the same experience?

The symptom is that I sometimes get the correct exit status and  
sometimes a 255 - for the same repeated command. i.e.:

$ ssh -l root 192.168.0.202 true ; echo $?
0
$ ssh -l root 192.168.0.202 true ; echo $?
255

Using ssh -vvv shows that the debug message:

debug1: client_input_channel_req: channel 0 rtype exit-status reply 0

is missing if ssh returns 255, i.e. dropbear does *not* provide the  
exit status and the client substitutes -1.

This appears to me to be the same bug as in the Changelog (although  
OpenMoko komes with version 0.49)

Does anybody know a fix or is dropbear broken? Or is OpenSSH  
available for OpenMoko?
