Nokia :: E-Mail Signature Grey And Single Line After PR1.2

After having updated my N900 to PR1.2, I now find that when I reply to, or create a new message in the standard e-mail client , my automatic signature is inserted in grey instead of black, and all linefeeds are left out so the whole thing appears in one line instead of four which is how I have it.Sure, I can edit it and re-insert the linefeeds and make it all black, but this is clearly not the point. It worked fine prior to 1.2 and should continue to work fine after the upgrade.

One quirk of this 'bug' is that, once I've opened a new message (with the incorrect signature), if I change the originating e-mail address (I have more than one e-mail account) by tapping on my e-mail address at the top and selecing a different one, the signature 'repairs' itself and the linefeeds re-appear so the signature then looks fine except that it's still in grey.
