Scilab xcos hangs on HDF5 error

[Brent Miller]

Every time I try to run an xcos simulation, xcos will hang. When I start scilab from the command line I get:

$ scilab

(process:3761): Gtk-WARNING **: Locale not supported by C library.
 Using the fallback 'C' locale.

And I will have to kill the scilab-bin process in order to get scilab to stop. If I run the same .xcos file in the Windows version (5.3.3) it works fine.

In order to reproduce:
launch scilab
From the menu select Applications->xcos
Create a simple simulation (for example, a ramp function, a scope, clock, and CLINDUMMY_f) or use the attached file
Push the run button on the main xcos window.
Xcos will display "Simulation in progress..." in its status bar
The above HDF5 error will be output to the command line
All of the scilab windows will be unresponsive, requiring killing the process.
