Hi all,
I am getting the following error when trying to connect to a Windows 7
machine via RDP from a Debian Wheezy system with Guacamole 0.9.9
installed. It's been compiled with RDP and SSL support.
When running guacd in the debugger (gdb), it does not crash (!). In all
the other cases:

Using tcpdump, I can see the connection on localhost to guacd, and also
the connection from localhost to the Win7 machine in question. However,
for some reason the connection isn't carried out the end.
Couldn't find any errors in Event Viewer on the Win7 host in question.
Guacd is segfaulting:
Jul 20 22:27:48 guac kernel: [10017.627627] guacd[3787]: segfault at
7fc59b0772e0 ip 00007fc59b0772e0 sp 00007fc5982e9c68 error 15 in
libguac-client-rdp.so.0.0.0[7fc59b077000+6000]
Is this some kind of timing issue since running in the debugger (slower)
is ok?
Thanks,
Marki
