When trying to start italc (master) application after launching ica (client), ica crash with signal: 11.

Here the command-line output of ica :

25/03/2014 15:56:37 To disable this behavior use: '-noxdamage'
25/03/2014 15:56:37
25/03/2014 15:56:37 Most compositing window managers like 'compiz' or 'beryl'
25/03/2014 15:56:37 cause X DAMAGE to fail, and so you may not see any screen
25/03/2014 15:56:37 updates via VNC. Either disable 'compiz' (recommended) or
25/03/2014 15:56:37 supply the x11vnc '-noxdamage' command line option.

25/03/2014 15:56:37 If this yields undesired behavior (poor response, painting
25/03/2014 15:56:37 errors, etc) it may be disabled:
25/03/2014 15:56:37 - use '-nowf' to disable wireframing completely.
25/03/2014 15:56:37 - use '-nowcr' to disable the Copy Rectangle after the
25/03/2014 15:56:37 moved window is released in the new position.
25/03/2014 15:56:37 Also see the -help entry for tuning parameters.

25/03/2014 15:56:37 Scroll Detection: -scrollcopyrect mode is in effect to
25/03/2014 15:56:37 use RECORD extension to try to detect scrolling windows
25/03/2014 15:56:37 (induced by either user keystroke or mouse input).
25/03/2014 15:56:37 If this yields undesired behavior (poor response, painting
25/03/2014 15:56:37 errors, etc) it may be disabled via: '-noscr'

******************************************************************************
Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval. It should work with any VNC viewer. Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.
