            Bug ID: 13828
           Summary: Scilab stop reacting to key presses and dumps core
                    when quitting
           Product: Scilab software
           Version: 5.5.1 final version
          Hardware: PC
                OS: Linux_x64
            Status: NEW
          Severity: Medium
          Priority: P5

BUG DESCRIPTION:
----------------

Scilab sometimes stop reacting to key presses, whatever GUI part has the focus (console, scinotes, a figure window, ...).
The GUI still reacts to mouse events.
If scilab is closed, a core is dumped.
It occurs few times a week but I did not find a reproducible way to trigger the bug.
