Split from bug 874546.

STR:

1) go to http://people.mozilla.com/~nhirata/html_tp/big_buck_bunny_480p.webm
2) Press home.
3) Go to task manager and back to Fennec. (repeat 2-3 a few times if needed)
4) Observe Compositor crash:

F/MOZ_Assert(  771): Assertion failure: IsCurrent(), at ../../../dist/include/GLContext.h:1441
F/libc    (  771): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1), thread 861 (Compositor)

Likely due to some attempt to thumbnail the page, see the backtrace in:
https://bugzilla.mozilla.org/show_bug.cgi?id=874546#c16
Reproduced on:
http://ftp.mozilla.org/pub/mozilla.org/mobile/tinderbox-builds/mozilla-inbound-android-debug/1370348773/fennec-24.0a1.en-US.android-arm.apk

Normal Nightly doesn't crash as it doesn't contain the failing assertion check.
