Comment (by boklm):

 I didn't try to do some debugging yet, but after looking at the HTTPS
 Everywhere code, I am wondering if it could be caused by the
 NSS.initialize function:
 https://gitweb.torproject.org/https-
 everywhere.git/tree/src/chrome/content/code/NSS.js?id=7035dde6b76eb8be458d410768188d9cd5d09f89#n28

 {{{
   try {
     sharedLib = tcypes.open(nssPath);
   } catch (e) {

 }}}

 when `nssPath` is empty when called from:
 https://gitweb.torproject.org/https-everywhere.git/tree/src/components
 /ssl-observatory.js?id=7035dde6b76eb8be458d410768188d9cd5d09f89#n126
 {{{
   try {
     NSS.initialize("");
   } catch(e) {
 }}}
