Looking at the signatures via the Evolution signature editor everything looks fine. However in email send out everything from the -- separator down is on a single line. I am not sure exactly when this started happening in the version in Fedora Rawhide, but it doesn't for the Evolution version in Debian Sid.
Hi, It's already under the radar and will be fixed in the next version.
That great, thanks. BTW "under the radar" means it cannot be seen, perhaps you meant "on the radar"?
