http://mxr.mozilla.org/mozilla-central/source/dom/dom-config.mk?mark=1-1&rev=bd1411e362fb sets MODULE=dom which overrides http://mxr.mozilla.org/mozilla-central/source/dom/plugins/base/Makefile.in?rev=15bfad783467&mark=45#37 causing it to overwrite dom.xpt from http://mxr.mozilla.org/mozilla-central/source/dom/base/Makefile.in?rev=15bfad783467&mark=45-45#37 . Found this because I had silly code walking all interfaces and didn't deal with failure correctly. It failed looking at nsIBufEntropyCollector because the parent interface failed to resolve. Will attach a patch in a second, I need a bug number for the proper commit message first :)
