This needs to changed to OS_LINUX, but we don't won't to remove this code
completely.

but ui/gfx/gtk_util.h doesn't exist anymore and gfx::GtkInitFromCommandLine) is
now in chrome/browser/ui/libgtk2ui/gtk2_util.h. Do you want me to copy it out
here instead?

[Sergey Ulanov, 2014/06/10 06:05:55]

We can't depend on src/chrome here. Please replace gfx::GtkInitFromCommandLine()
with  gtk_init(NULL, NULL), same as in
remoting/host/it2me/it2me_native_messaging_host_main.cc .
Thank you!

Done.

-  // Required for any calls into GTK functions, such as the Disconnect and
-  // Continue windows, though these should not be used for the Me2Me case
-  // (crbug.com/104377).
-  gfx::GtkInitFromCommandLine(*CommandLine::ForCurrentProcess());
-#endif  // TOOLKIT_GTK

   // Enable support for SSL server sockets, which must be done while still
   // single-threaded.
   net::EnableSSLServerSockets();
