Description

[Martin Thomson [:mt:]]

Thank you for helping make Firefox better. If you are reporting a defect, please complete the following:

What were you doing?

Nothing.

What happened?

Browser console shows lots of this same message:

TypeError: "undefined has no properties"
    _setupHarTimings resource://devtools/server/actors/network-monitor/network-observer.js:1199
    _onTransactionClose resource://devtools/server/actors/network-monitor/network-observer.js:967
    _dispatchActivity resource://devtools/server/actors/network-monitor/network-observer.js:502
    observeActivity resource://devtools/server/actors/network-monitor/network-observer.js:576
    makeInfallible resource://devtools/shared/ThreadSafeDevToolsUtils.js:111
ThreadSafeDevToolsUtils.js:90:13

What should have happened?

Not displaying this message.

Anything else we should know?

Not really.

@Martin: I don't see such warning in the Browser Console (or should I be looking somewhere else?)

Could you please provide some steps we could follow to reproduce the warning on our machines?
Without such info it's hard to take an action.

For example:

1. Open the DevTools toolbox
2. Select the Network panel
3. Load this page: ...
4. Perform this action ...
5. etc.

Thanks!

I wasn't able to reproduce this just now, but here's what seems to have worked...

Start browser
Open browser console (Ctrl+Shift+J on my machine)
Get nightly update
Apply nightly update (i.e., restart the browser)

The browser console is open again when I restart and it instantly produces an unending stream of these error messages.

Thanks for the update!

I followed steps from comment #2 and saw the following exception in the Browser Console:

It isn't the same as reported, but something weird is happening.
