Icon dimensions (0x0) don't meet the the size requirements

Got a weird warning while validating my FontType 1.1 update at the weekend:

iPhone/iPod Touch: Icon dimensions (0x0) don't meet the the size requirements. The icon file must be 57x57 pixels, in .png format

Icon was just fine, so it's unclear what this means. However there are two theories: a) latest Apple iOS update messed up something or b) Apple iTunes Connect server has some issues.

Application Failed Codesign Verification

Submission to App Store wasn't as easy as I thought in previous blog. Not really surprised, but this problem was tough to solve. Not tough as in hard to fix, but as hard to figure out:

Application failed codesign verification.  The signature was invalid, or it was not signed with an Apple submission certificate. (-19011)

Build & Archive - Share Application - CSSMERR_TP_NOT_TRUSTED

Build & Archive - Share Application and both Email and Save fail without any visible error note. You seem to have been simply ignored. Try again to be totally ignored.

Possible error notes you can find from Console application - Databases searches - Console Messages:

•     Command /usr/bin/codesign failed with exit code 1
•     CSSMERR_TP_NOT_TRUSTED

Open Keychain Access, go to "login" keychain "Certificates" catogory. Open each development related certificate (Apple WorldWide Developer Relations Certification Authority, iPhone Developer, iPhone Distribution) and make sure their Trust details are "Use System Defaults".
