I think this works out correctly -- we'll reject the gradient expression (as we should, since it's invalid).

The JS-error-spam is annoying, but we'll be deprecating the CSSUnprefixingService soon (and won't be shipping it globally-enabled to any release versions ever, I think), once bug 1213126 lands.

So, to the extent that there's something to fix here, it's upstream css-fixme, where this webkit-gradient unprefixing script comes from. ( https://github.com/hallvors/css-fixme/ )

...though I can't trigger this error (in my error console) when pasting the testcase's webkit-gradient CSS into http://hallvord.com/temp/moz/cssfixme.php .  So maybe the upstream version doesn't get tripped up by this after all? Cool.

Anyway: given that this is just about some console-spew, in a JS-implemented service which is going away and which is only enabled by default on whitelisted sites anyway (for release builds), I'm going to say this is WONTFIX.
