One allnigher later, its to late for opinions. Implemented with:

http://cgit.freedesktop.org/libreoffice/core/commit/?id=74f44646ba5b400cc39d78940677f136711459b5
http://cgit.freedesktop.org/libreoffice/core/commit/?id=279473f1ed6cd3bb6f6d2b8b9c75529b91836e39
http://cgit.freedesktop.org/libreoffice/core/commit/?id=1cec66388eac81af2197da4fbf8fd2b00c56c7a5
http://cgit.freedesktop.org/libreoffice/core/commit/?id=a1b57be652ac532ebddb3e3e53dddc35ae420f31

Still might need some tuning (core file location for example,
superfluous gdb output), but it basically works:

 ulimit -c unlimited && make subsequentcheck

gives you a full soffice stacktrace:

While only showing the essentials of the Java stacktrace:

and a hint at the full log:
