[Linux] Fix opening RealPlayer from menu

In Firefox register rtsp portocol:
about:config

Create a new name:
network.protocol-andler.external.rtsp
value set to 'true'

network.protocol-handler.app.rtsp
value set to the location of your realplayer (e.g. /usr/bin/realplay)

Install realplayer:
sudo apt-get install realplayer

If you cannot open RealPlayer from the start menu, it is conflicted with Scim.

To fix the problem:
Modify the file: /usr/bin/realplay

Find:
#!/bin/sh

after ADD:
GTK_IM_MODULE=xim ; export GTK_IM_MODULE
