[Libreoffice] 3.4rc1: new segfault in build process

Something I haven't seen in 3.4beta5:

R=/build/src && S=$R/build && O=$S/solver/340/unxlngx6.pro && W=$O/workdir &&  mkdir -p 
$W/Module/check/ && touch $W/Module/check/svl
        zip warning: help.jar not found or empty

Any idea what commit broke this? 

Is this related to a certain LibO extension that I can disable for now?
