This job appears to have run correctly:
https://integration.wikimedia.org/ci/view/BrowserTests/view/VisualEditor/job/browsertests-VisualEditor-language-screenshot-os_x_10.10-firefox/LANGUAGE_SCREENSHOT_CODE=fa,label=contintLabsSlave%20&&%20UbuntuTrusty/25/console
However, it is marked as failure. It repeatedly happens for language "fa".
Looking at one of the job:
00:36:23.487 Performance: File TEST-features-language_screenshot.xml reported 0.0% of errors [SUCCESS]. Build status is: FAILURE
Might be a weird issue with the Jenkins Performance Plugin we have enabled on browser tests. There is not much information in the log though.
Looks like this is the problem:

Looks like somebody redirected VisualEditor_Formula_Insert_Menu-fa.png to VisualEditor_Insert_Menu-fa

@Amire80: I have assigned the task to you, since we have found the problem. Could you please assign it to someone that can fix the problem, or create a subtask? Thanks.
One of the files was a redirect to another file. This confused the uploading API, so it raised an exception that rendered the whole job red. And this is actually correct, but was kinda hard to find :)
@Elitre deleted the redirect, and now it works well.
