404 Not Found: officeotron-0.7.4-master.jar

I do not think by backtrace for:
http://nabble.documentfoundation.org/export-validation-in-tests-by-default-causing-32-bit-Ubuntu-to-crash-tp4192925p4193137.html

was useful, so I tried track down the cause of this regression by doing a build before https://cgit.freedesktop.org/libreoffice/core/commit/?id=0868f670374cdcf6c2610d91ff8702f59b2e0bd3

With 

--enable-ext-validator
--with-export-validation
--enable-symbols

And I get the following Error:

Is there any point in trying to further bisect this regression or should we focus on getting a good backtrace?
