Reload http://player.twitch.tv/?channel=<some_live_channel> with dev tools open.

In browser console error shows up (form resource://devtools/server/main.js:1611): 

error occurred while processing 'resolveLocation: CompileError: at offset 0: failed to match magic number

After that dev tools cannot be closed. Looks like all panels are destroyed (TypeError: webconsolePanel is null) when changing tabs. But debugger one is still alive so I assume it prevents to close dev tools. 

It is easily reproducible so you will figure it out in no time :)

Can't seem to reproduce in Nightly but I can see it breaking in Release; but not crashing.  Reopen this if the error persists.
