Failing to build Android, iOS fine

I’m making use of Cross Platform Native Plugins (https://www.assetstore.unity3d.com/en/#!/content/31086) from the store and ever since they recently updated it to 1.2.1 my Android build has failed to compile on UCB with this error.

These files (nativeplugins.png and notification.mp3) are located in the StreamingAssets directory if that’s any hint, maybe UCB doesn’t support having files in StreamingAssets?

Seems to me it might be trying to compile some SVN junk left around into the APK and it get’s angry at there being multiple files with the same name (but different extensions). I thought maybe a clean build of Android would help but no luck. Any ideas?
