Crash happens with ESR and Aurora channels and it's spurious and non-trivial to reproduce.

A similar crash happens if you download a stream's media file and the http server throttles the download to similar unusual staggering rates regardless of media file size.

To be sure I tried with ESR (24), current stable (27), Aurora (29) and Nightly (30)
and it's possible to make long and staggering downloads crash all versions.
Both i386 and x86_64. I believe this is a new bug introduced in the last 6 months
if I'm not mistaken.

Please follow the steps on http://support.mozilla.com/kb/Firefox%20crashes and report back here - we need a stackcrashid here.

Unfortunately I cannot produce a crash report but here's a sure way to reproduce which you hopefully can replicate with your network simulation tools in the qa lab.

Start at least 3 or more slow and staggering downloads of files that take more than an hour to download. Think 500MB or 1GB at 60kb/s taking 2 or hours.

Have you see this since?
It's hard for us to do anything without a stack

There's a few in https://bugzilla.mozilla.org/buglist.cgi?v4=download&f1=short_desc&o3=substring&list_id=11995655&short_desc=crash&v3=download&o1=nowordssubstr&j2=OR&classification=Client%20Software&classification=Components&op_sys=Linux&f4=short_desc&chfieldto=Now&query_format=advanced&chfieldfrom=2y&f3=component&f2=OP&o4=substring&short_desc_type=allwordssubstr&product=Core&product=Firefox including some which were fixed

I was planning to ask if this was fixed and today I read Daniels Stenberg's blog and believe one of his fixes is responsible for me not having seen this in a long time. Thank you Daniel and everybody involved.
