haroopad not starting on debian 64

I have just downloaded haroopad on my Debian 64 box where firefox and chromium run.

haroopad does not start at the command line and I get the message

[6885:0628/072328:ERROR:browser_main_loop.cc(162)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.

ATTENTION: default value of option force_s3tc_enable overridden by environment.
