#595 gnuplot_x11 segfault 2

[Peter Schiffer]

Hello,

under certain circumstances, when suspending and then waking up notebook, "plot" variable in process_event() function in gplt_x11.c file can be null. This can lead to segfaults. Proposed patch fixes the problem.

More information about this bug with backtrace can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=812225

Thanks,

peter
