Reproduced with current pine/kanikani, on a B2G_DEBUG=1 build for Z3c. STR: 0. load google.com 1. focus in text field We see keyboard appearching then replaced by black area and a notification of a crash.

This also gets reproduced on Mulet (debug build) when enabling OOP.

This assert is hit at: https://hg.mozilla.org/projects/pine/file/58921658aef9/dom/workers/WorkerPrivate.cpp#l4366 because the condition at https://hg.mozilla.org/projects/pine/file/58921658aef9/netwerk/base/nsNetUtil.cpp#l586 is false. The false comes from: contextInIsolatedBrowser=1 while we have principalInIsolatedBrowser=0

This means mOriginAttributes.mInIsolatedMozBrowser in caps/BasePrincipal.h is false. Does it makes sense ?

Hmm, I don't know this code at all :-/ It does look weird, but I'm afraid I don't really understand what's going on. Maybe ckerschb can help out?

My understanding is that when checking the appId and browserElement, the browser flag doesn't match what's expected because it's not an app/process supposed to be in the browser. Since it's appearing when you focus on the keyboard, couldn't it mean that the keyboard is set to be "not" in the browser (which could sound legit)? I don't know if that should be the case or not, I will look more thoroughly in the code.

This happens when we are building a worker, at https://github.com/mozilla-b2g/gaia/blob/fe929e5a4be3e06964655e5ce0aa75a86b583466/apps/keyboard/js/imes/latin/latin.js#L357

Disabling keyboard autocorrection and prediction works around the issue.

(In reply to Frederik Braun [:freddyb] from comment #4) > Maybe ckerschb can help out? Sorry, I am not an expert within worker code. Probably Kyle knows why you hit the assertion within workers/WorkerPrivate.cpp#l4366.

You need to figure out why the principal and the load context don't match, and where they're coming from. I don't have any more insight than that, and I don't have any time to spend on unsupported products, sorry.

Marking as fixed-in-pine thanks to workaround in bug 1266064
