When link like mailto:email@example.com are opened in Sylpheed, field To: contains address without "+".
I use Sylpheed 3.4 b7.

This isn't actually a bug. According to RFC 6068 "The 'mailto' URI Scheme" the + sign should be URI encoded. Sylpheed does the right thing and URI decodes the email address which leads to replacing all + signs with spaces.
The correct encoded mailto link should be mailto:cketti.apps%2Battachcontact@gmail.com
1. A number of characters that can appear in <addr-spec> MUST be percent-encoded. These are the characters that cannot appear in a URI according to [STD66] as well as "%" (because it is used for percent-encoding) and all the characters in gen-delims except "@" and ":" (i.e., "/", "?", "#", "[", and "]"). Of the characters in sub-delims, at least the following also have to be percent- encoded: "&", ";", and "=". Care has to be taken both when encoding as well as when decoding to make sure these operations are applied only once.
