Why do I receive an error when I plot matrix signals from the Fixed-Point Settings interface in Simulink 6.0 (R14) ?

When I try to plot the matrix signal from the Fixed-Point settings interface, I receive the following error:
??? Error using ==> plot
Data may not have more than 2 dimensions.
Error in ==> fxptplt at 188
plot(data{:})
??? Error while evaluating uicontrol Callback.
To reproduce the problem, follow the steps below:
1. Open the attached model 'fixed_matrix_plot.mdl' and run it once
2. Go to 'Tools -> Fixed Point Settings' to bring up the Fixed-Point Settings interface
3. Click on 'Show Plot Dialog' on the figure's toolbar, the last button on the right
4. Click on 'Plot Signals' button
