1042628 - Firefox quits unexpectedly after closing the shared window item

Status: RESOLVED DUPLICATE of bug 1045482

(Core :: WebRTC, defect, P1)

Description

[Bogdan Maris, Desktop QA]

Latest Nightly 34.0a1 (buildID: 20140722030201)

STR:
1. Open Firefox
2. Set media.getusermedia.screensharing.enabled to true
3. Open http://queze.net/goinfre/ff_gum_test.htm in a new tab
4. Click Window&Audio
5. Open Window or screen to share dropdown and select something that can be closed afterwards (eg: a folder)
6. Click Share Selected Items
7. Close the item that was shared (eg: a folder)
8. Open Web Console (ctrl/cmd+shift+J)

Expected result: A message appears that says connection lost, an error message or something.

Actual result: Firefox quits after a few seconds without crash report.

Notes:
1. This is Linux only.
2. On Windows the share screen remains stuck on the item that was shared. I left the browser opened with the screen stuck for about 1 hour and I got a crash:

bp-701bebec-cac8-4c7a-9f4b-76b362140723
bp-39af1c3b-46c3-401b-acad-e80122140723
bp-e3ff51a3-2f81-4578-a56a-29cef2140723

I can open a new bug for this crashes.

3. On Mac the share screen turns black (which I think should be expected result) but 'Success!' message is still there.

Bogdan -- Thank for you the bug reports on screen and window sharing!  When you file a bug against screen/window sharing, can you make it block bug 1040061 (that's the meta bug for screen/window sharing in Fx 33).  Thanks!

gcp or Matt -- Can either of you take/own this bug? It was just found overnight and would block screen/window sharing in Fx 33.

This is now 404.  Is there another test url that can be used to reproduce?

It hasn't moved, but there was a typo in comment 0: .html not .htm

SInce this is reported as Linux-only, dup to the X11 error bug
