"This plugin does not have a valid header" message

[DevinWalker]

Issue Overview

This has been reported a few times in the last 2-days:

Themefuse also wrote today to report that their users have experienced the same:

Steps to Reproduce

1. Fresh WP install on PHP >5.6
2. Goto WP-Admin > Plugins > Add New
3. Search "Give"
4. Install and Activate

You should see the message. Oddly enough, when you activate on the plugins sceen it appears to activate fine.

Expected Behavior

Activates properly without issue.

Findings

I discovered the issue appears to be when we released 1.6.3 the plugin's trunk somehow got added to the tag:

This is causing the activate link within WP plugin's directory search to point to an incorrect give.php file:

I believe this has to do with our deploy script perhaps running twice.

Solution

Remove the trunk from 1.6.3 and release 1.6.4

I'm releasing 1.6.4 and will resolve the issue in SVN in the process.
