it seems that toolkit/components/extensions/test/xpcshell/test_ext_downloads_misc.js is permafail when running on linux32 in a docker container (a linux64 container with :i386 libraries and a 32 bit firefox downloaded). I believe all tests using mozicon are failing and it is not clear how to make this work. I am not sure if this test provides a lot of value for linux32, if it does- we would need some help from the test owner to figure out how to get this working.

I see this fail as well: dom/security/test/mixedcontentblocker/test_bug803225.html this is from: https://treeherder.mozilla.org/#/jobs?repo=try&revision=d5f5bbdb7199a2c3f89e473f441aadd819d1d2ce&filter-tier=1&filter-tier=2&filter-tier=3&exclusion_profile=false&selectedJob=33245381&filter-searchStr=linux%20mochitest-e10s-5 it seems to be e10s only.

These lines look relevant: 16:53:31 INFO - PROCESS | 9932 | (xpcshell:9932): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:60:17: Theming engine 'unico' not found 16:53:31 INFO - PROCESS | 9932 | Gtk-Message: Failed to load module "canberra-gtk-module"

Thanks Kris - I had not noticed those. I was able to eliminate those error messages by installing: gnome-session-canberra:i386 gtk3-engines-unico:i386 libcanberra-gtk-module:i386 libcanberra-gtk3-module:i386 but the test continued to fail in just the same way: https://treeherder.mozilla.org/#/jobs?repo=try&revision=ff42afaf55885e9b13ba1335b68728e748fb4657. I also tried some different combinations of these and other gtk/canberra/unico packages but without success. I think I'll simply skip the 2 tests (test_ext_download_misc.js and test_bug803225.html) on linux32 only - that seems like a minimal loss of test coverage to me.
