Exporting IPA xCode 7 Crashes immediately

Question

Working on a project for a client who has sent me provisioning profiles and certificates. Trying to export and "use local signing assets" but then xcode crashes immediately. Everything worked fine when I was running iOS 8 / xCode 6.4 / Yosemite, but after upgrading to iOS 9 / xCode 7 / El Capitan I can't export the archive anymore.

Any ideas?

Confirmed by Apple it is a bug with xCode 7.
