By the definitions on <http://bugzilla.mozilla.org/bug_status.html#severity> and <http://bugzilla.mozilla.org/enter_bug.cgi?format=guided>, crashing and dataloss bugs are of critical or possibly higher severity. Only changing open bugs to minimize unnecessary spam. Keywords to trigger this would be crash, topcrash, topcrash+, zt4newcrash, dataloss.

nsClipboard::nsClipboard does not call Init anymore. STR above gives me: uncaught exception: [Exception... "Component returned failure code: 0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]" nsresult: "0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)" location: "JS frame :: typein :: <TOP_LEVEL> :: line 1" data: no] which is an acceptable result according to reporter. -> WORKSFORME
