Subject: x2agent segfault in LibNX_X11.so when disconnecting

Date: Wed, 2 Sep 2015 09:14:50 -0500

[Message part 1 (text/plain, inline)]

Package:  x2goagent

Version:   3.5.0.31-1.el6

 

When I disconnected from a windows client, I lost my session.  This is the
result in the server at the time of the disconnect.  It does not happen
every time, just some times when I disconnect.  I can re-connect fine with a
new session, but the running session is lost.

Hi,

ok, not exactly the same problem in my case like james.

x2goagent  crashs  from time to time while working with thunderbird or
jdownloader.
