Please describe the problem.

The watcher crashes.

I only need to restart the thread in the pop-up to get everything to work again, but I'm reporting just in case that this issue has any other implications.

What steps will reproduce the problem?

I open the webapp and in the minutes before it starts syncing (syncing is enabled) I disable it (clicking in the 'syncing enabled' text).

This produces a crash every time.

What version of git-annex are you using? On what operating system?

5.20140320 in Debian sid and testing

Please provide any additional information below.

This is all I can see in the logs
