Xcode 4 archive results in slow/unresponsive Organizer & pngcrush process takes up 100% cpu

sorry about the rather confusing title, but I tried to get in as much info as possible.

Problem:

  1. I'm trying to archive my iPhone app into an ipa file for OTA testing (via TestFlightApp) - so in Xcode, I perform a Project > Archive.
  2. After the archive is successful, it opens the Xcode Organizer to create the ipa file. BUT as soon as Organizer is opened, Xcode becomes VERY slow & essentially unresponsive.

So naturally I open Activity Monitor to see what's going on and there's a process called "pngcrush" using up almost all my cpu (90%+) and causing Xcode process to be intermittently listed as "not responding". I can't seem to do anything in Organizer because it just keeps throwing the spinner/loading cursor.

Any ideas on how to fix this would be great! Also, I've tried setting "Compress PNG" option in build settings to NO, but problem is still there. Thanks!

Xcode 4.0.2, OSX 10.6.6

This is a weird bug.

I found the way I solved it was by deleting the launch images from the bundle and then adding the images normally, though, the add files interface. If I dragged the images into the summary pane on the application target, it cause the large image to show up in the organizer preview image which PNGCrush is constantly trying to shrink.

I found it by deleting the icon and/or launch image file as well as moving the archives with the offending icon/launch image files. I also found, the launch image file was 20px too small as I trimmed for the status bar which is incorrect.

For some reason my Info.plist file had multiple (some invalid) entries for Icon files and Icon files (iOS 5). I removed all the items in these lists, re-added the app icon, and everything seemed to start performing well again. Hope this helps someone else!
