Steps to Reproduce


graphics_toolkit qt
demo semilogx 3
# Choose Pan tool and pan graph


I get the following messages on stderr 


octave:2> error: set: "xlim" must not be nan
terminate called after throwing an instance of 'octave::execution_exception'
fatal: caught signal Aborted -- stopping myself...
Abort (core dumped)


If I run with the FLTK toolkit I get 


octave:3> error: set: "xlim" must not be nan
error: parse error
octave:3> error: set: "xlim" must not be nan
error: parse error
octave:3> error: set: "xlim" must not be nan
error: parse error


but at least Octave does not segfault.
