Description of problem:
scp can upload files from my new F12 box, but not download - it just stalls. Similarly, uploading to the F12 box stalls after reporting some amount of file sent (actually, destination file is 0 bytes).

How reproducible: every time


Steps to Reproduce:
[root@yggdrasil ~]# scp yum.list kostya@mireille:~
kostya@mireille's password: 
yum.list                                      100% 1528KB   1.5MB/s   00:00    
[root@yggdrasil ~]# scp kostya@mireille:~/yum.list yum.list.2
kostya@mireille's password: 
yum.list                                        0%    0     0.0KB/s - stalled -^CKilled by signal 2.


Additional info:

The F12 box is x86_64 installed from prerelease LXDE live CD and yum update'd to current.
Package openssl is ver. 1.0.0-0.10.beta3.fc12
Originally it was listed as @rawhide, but after yum reinstall it now lists @fedora instead.

I've tried disabling the firewall, and tried multiple remote machines to copy files to.
