[jira] [Comment Edited] (TS-2351) Range request crash in 4.1.x

---------------------------------------------------------------

I think this is a duplicate, although I can't recall offhand which bug. IIRC the problem here is that this shouldn't be in the range setup logic at all and as a result it crashes on that line because s->ranges is bogus. I'll try to do some more investigation.
