[X2Go-Dev] Bug#377: paramiko fails to recognize known_hosts

[Jan Engelhardt]

strace reveals this:

2844  open("//.ssh/known_hosts", O_RDONLY) = -1 ENOENT (No such file or
directory)

Looking at the environ of a newly-started x2gobroker:

# hexdump -C /proc/20044/environ
00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|
*
00000840  00 00 00 00 00 00 00                              |.......|
00000847
#

So the environment was modified inside python and I have no
further clue on what its actual state is, whether the environ
array just moved in memory (plausible), or destroyed in-place
leaving nothing for paramiko.
