gpgme and signature comments

This may be a shot in the dark, but is anyone else having issues with
adding comments to a GPG ascii signature when signing through gpgme? 

I would like to add a comment to my e-mail sigs when signing with my mail
program (Sylpheed-Claws) which uses gpgme. As seen below, the comment does
not appear. However when I sign a file with gpg directly the comment
appears as normal. At first I thought that the issue was caused by
Sylpheed, but the developers there have pushed the blame to gpgme. Is this
really an issue and if so is there any way around it?

Thanks,
