Error on Tail all action with already tailing document

[Google Code Exporter]

What steps will reproduce the problem?
1. Open a file and start tailing 
2. Press the Start tail all button
3. Click or scroll into the Log Viewer content.

What is the expected output? What do you see instead?
The content gets empty or the attached stack trace opens. 

I attached a workaround, that checks if an document is already tailing. It 
would be better to grey out the tail all button if all documents are already 
being tailed, but i do not know if this can be achieved easily.
