Data goes to console instead of Octave GUI command window

[PrasannaKumar Muralidharan]

Hi,

Installed latest octave code from hg (18030:f0427ca399cc). Did the
following in Octave GUI

>> x = sym('x');
>> plot(Sin(x))
error: unary operator '.'' not implemented for 'ex' operands
error: called from:
error:   /usr/local/share/octave/3.7.7+/m/plot/draw/private/__plt__.m
at line 185, column 8
error:   /usr/local/share/octave/3.7.7+/m/plot/draw/private/__plt__.m
at line 118, column 17
error:   /usr/local/share/octave/3.7.7+/m/plot/draw/plot.m at line
220, column 10
>>

After that all the command that I type does not appear in the GUI
command window, it appears in a terminal from which Octave was
launched.

Should I report this as a bug?

Thanks,
PrasannaKumar
