The recent changes of always auto-generating components.manifest/interfaces.manifest files and including them in the chrome.manifest file have led to the situation that xforms defined its components once in the chrome.manifest and once in the components/components.manifest. This causes Firefox to crash on startup with the attached backtrace.
Unfortunately I couldn't think of an possibility to reproduce this bug without XForms (even though its not xforms specific, it should be present with every extension that uses manifests). The xforms code is a bit hard to build ATM due to various core changes, so I attached a bash script that downloads and patches all components to make reproducing this bug easier. It's attached as reproduce-manifest-bug.sh
To reproduce this bug:
./reproduce-manifest-bug.sh
cd manifest-bug/mozilla-central
MOZCONFIG=../mozconfig make -f client.mk build
Then simply start firefox and it should crash.
The first couple "Re-registering a CID" messages are harmless (libschemavalidation.so is found twice due to some build wiredness)
