This is one of the strangest ones ever for me.

I noticed this against 9626; it seems to be a problem with all versions since the shift from dropbear 0.49 to 0.50.

I get the oops shown below ONLY in the case that I ssh into my openWRT box (a Netgear WGT634U) and then try to ssh back out again.

However, and this seems completely reproducible, if I ssh in as root, then su to another user, things work just fine.

I'm going to assume it must be permissions-related somehow, but dang if I can figure out how.

FYI.  I'll be glad when this goes away.
