Updating version, and also setting target to 3.1.0, in hopes this can be fixed
before official release. If not, should be scheduled for 3.1.1

Daniel, does that actually work as a link? (If so, what mail program are you using?)

Moving to 3.1.1.

umm, how the hell does that work?  *does* that work in any MUA?

'hLOPDKDWUZKEMWCNLMKEKIIRIZOUKOXYIAKBBNJQAGDNUHLAIVLZQQJWXOLWBRPTXSIUSDREJGWJSZVLMZWFMEHOULBUDCMAJHHBZCLZLWWHFEBTUFOSTGKRDMBWYHITRROACYQKGNSNSFWVOPHERZAWKp:'
is certainly not a valid URI protocol spec ;) but if it does work we have to
catch it.

having heard nothing, I'm going to close out this ticket.  as far as we know, the URL specified won't 
actually work in an MUA/browser.  If this isn't the case, please let us know what programs accept these.  
Thanks.
