1342919 - taking screenshot fails silently

Status: RESOLVED DUPLICATE of bug 766661

(DevTools Graveyard :: Graphic Commandline and Toolbar, defect, P2)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Tested on latest Firefox 54.0a1 + 53.0a2 on Windows 8.1

Trying to capture a screenshot by clicking the screenshot button in the Developer Toolbox
a) succeeds on https://wiki.mozilla.org/
b) fails on https://planet.mozilla.org/
c) often fails, but sometimes succeeds for http://www.tagesschau.de/

That it doesn't permafail c) is a point taken against bug 766661 comment 1 which mentions bug 591822.

Error console contains:

Object { isTypedData: true, data: Object, type: "error" }  cli.js:2056
Object { columnNumber: 0, lineNumber: 308, message: "", stack: "createScreenshotData@resource://gre…" }  cli.js:2056

The error gets thrown at https://dxr.mozilla.org/mozilla-central/rev/7ef1e9abd296a8edc39b7efc8d637767ba2f77ed/devtools/shared/task.js#387-388

Suspecting a duplicate of 766661, I'm afraid.
