[Octave-bug-tracker] [bug #48081] qt graphics toolkit plotting error: octave_base_value::convert_to_str_internal (): wrong type argument '<unknown type>'

[Rik]

Update of bug #48081 (project octave):

                Category:                Plotting => Plotting with OpenGL   
                Priority:              5 - Normal => 3 - Low                
                  Status:                    None => Confirmed

Follow-up Comment #1:

Confirmed.  I'm attaching a slightly modified version of the script
(plot_string_error2.m) which runs the whole thing 10 times.  I rarely get
above 4 loop iterations before the error surfaces.  The error occurs only with
the qt toolkit--the others are tested and run fine.

This appears to have been fixed on the development branch.  I can't reproduce
it after running the test script multiple times.  I'm lowering the priority
because, absent an idea of where the problem is, it will be easier to just
move to the 4.2 release of Octave rather than discover exactly why this is
failing.  Also, there are workarounds just by switching to a different
toolkit.
