Réf. : Re: Crash at runtime (X Window System error) on Linux Xeon 64 bits

[frederic.bron at alcan.com]

Sorry for my previous message, it is not a problem with wxWidgets (wxGTK) but with openssh and cygwin.
I am logging to a remote linux server from windows/cygwin with ssh -X and this causes troubles. With ssh -Y it is fine !!! I do not really understand why but it works now.
Here is the link for others who could have the same problem: http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding
Thanks,
F. Bron

 You need to follow the advice of the error message and run the program
with --sync command line option under debugger and put a breakpoint on
gdk_x_error(). When the debugger stops there, do "bt" to see what's going
on, this should give some additional information.
