This happens on gmail, bugzilla, wikipedia, and a number of random websites that I've tried.  I'm using the 06/02 nightly.

I can't reproduce this on the 06/04 nightly. Where does "about:neterror" appear, in the script list? Does the error console show any errors? My theory is that when the debugger tries to fetch the scripts to display, it gets an error for some reason and can't get the file. Have you customized your browser network configuration settings in some way? Maybe the debugger code is not taking them into account.

This only happened once to me.  I don't have any specific customizations.  But about:neterror is what we show when there's an error processing the network request, so maybe that helps somebody to reproduce this?

I did not see anything interesting in the error console when this happened.

I tried disconnecting my network cable after loading the page, but before opening the debugger, but it works fine, since it gets the scripts from cache. I repeated the experiment with network.http.use-cache disabled and I got clear error messages in the error console. After reconnecting the cable or enabling the cache the scripts would load when switching to them.

I tried to reproduce this issue several times on the latest Nightly (2012-06-14), on Mac 10.7.4, in both 32-bit and 64-bit modes. I only got about:neterror in the scripts dropdown when loosing the internet connection while the page was loading. The page wasn't displayed either, so it makes sense it didn't actually get the scripts &co.

When the internet connection got back up, and I reloaded the page, the scripts were retrieved and displayed in the dropdown.

I tried this with gmail, bugzilla, wikipedia, yahoo and facebook.

Also tried to reproduce this yesterday, with the 13/06 Aurora and it went the same way.

Resolving this as we haven't been able to reproduce it, but feel free to reopen if it ever occurs again.
