I can't seem to reliably reproduce this problem.  When it happens usually closing the dev tools, reloading the page and re-opening the tools seems to fix the issue.

The last time it happened I took a look at the browser console and saw this error:
DevToolsUtils.js line 59

Handler function threw an exception: TypeError: info is null

This looks like the same error in Bug 1057031

Does the error happen only after a reload? If so, this is a dupe of bug 1057031.

I am not entirely sure as I have been unable to reproduce the error reliably.  I am not doing a ton of development over the next few weeks due to the holidays.  I would say close the bug and if I find that I can get it to happen without a reload I will submit a new one.

Thanks for following up, I think it's safe to assume this is the same problem as Bug 1057031 for now, but if you bump into it again feel free to reopen this one.
