Trying to enter a savannah bug report into the "See Also" field of bug 362949 will result in the following error message: https://savannah.gnu.org/support/index.php?107657 is not a valid URL to a bug. Please allow entering savannah bug reports into this field.
CC'ing upstream here as I think its an upstream bug.
Savane is not a bug tracker we currently recognize. The list of recognized BTS is here: http://mxr.mozilla.org/mozilla/source/webtools/bugzilla/Bugzilla/BugUrl/ It's very easy for you to add your own BTS into Bugzilla/BugUrl/.

*** Bug 567290 has been marked as a duplicate of this bug. ***
upstream has implemented this, so really we just need to cherry pick: 9f09d8dddd26ea38a9ea6bea3329dd8e33e3ba33 533b9c69b3f2214b708180527f69738cba0f80a8
(In reply to SpanKY from comment #5) and we need to enable the MoreBugUrl (as in bug 531276) the current Savane module doesn't cover all the cases i did, so i sent an update upstream for that https://bugzilla.mozilla.org/1229994
upstream has merged my patch now
change is live now in our tracker -- i've updated bug 362949 to include the savannah report in See Also
