It has been some time since I ran mozilla-central mochitests locally on Windows 8.1.

mach clobber
mach configure
mach mochitest --appname /f/Ablage/Temp/Trash/fx-useragent/firefox.exe browser_navigator.js

This fails with

0:52.88 INFO Checking for ssltunnel processes...
0:53.06 INFO Checking for xpcshell processes...
Error running mach:

['mochitest', '--appname', 'f:/Ablage/Temp/Trash/fx-useragent/firefox.exe', 'browser_navigator.js']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.
You can invoke |./mach busted| to check if this issue is already on file. If it
isn't, please use |./mach busted file mochitest| to report it. If |./mach busted| is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error

The details of the failure are as follows:

:ahal, could you have a look please?

Does this also happen without --appname?

Severity: -- → S3
Flags: needinfo?(ahal)

This fails because something is missing from the object directory:

  1. mach clobber && mach build && mach mochitest browser_navigator.js succeeds.
  2. mach mochitest browser_navigator.js --appname /f/Ablage/Temp/Trash/firefox/firefox.exe afterwards succeeds.
  3. mach clobber && mach configure && mach mochitest browser_navigator.js --appname /f/Ablage/Temp/Trash/firefox/firefox.exe fails.
