Does using http://symbolapi.mocotoolsstaging.net/ instead of http://symbolapi.mozilla.org work? If so, then this is caused by http://symbolapi.mozilla.org being broken at the moment.

There were two problems here: 1) The python-requests package used is broken. Upgrading it solved the problem. As I am predicting more people will have trouble with this, I submitted a patch to replace requests by urllib2. 2) The symbolication server was down, with the alternate http://symbolapi.mocotoolsstaging.net server worked.

vladan reported that the symbol server is back to normal. I made a test and it is working.

Comment on attachment 8616244 [details] Replace python-requests by urllib2 Looks reasonable to me.

The symbolication server kept going down, presumably because it was being spammed by odd symbolication requests. These requests had "Bolt" in symbolSources field and they always had the same stack with TaobaoProtectSE.pdb as one of the top frames. Do you know where these requests could have been coming from?

I just followed the instructions from :wcosta's blog post [1]. [1] http://walac.github.io/profiling-firefox-os-apps/

Nothing on my side. I will investigate and see if my changes screwed something up. I guess not, but double checking it won't hurt.

I made a test here and it is not related to B2G. As there is a pdb file in the request, I guess it is something related to Windows Desktop Firerox.

Thanks! I thought it might be a B2G emulator stack on Windows or something
