How can I solve the problem of icon error when uploading an application to App Store?

Released todayProgramTo the App Store. A strange error occurs:

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

The icons used by the program are in the standard PNG format, 57*57 and 114*114. However, the Application Loader of xcode still reports an error. Very puzzled.

For example:

Delete icon.png, add it again, clean, build, verify, or report an error. After Google, we found it was lion10. 7.3 bug (the system was updated to 10.7.3 In the afternoon ). You only need to reinstall the Latest Application Loader to solve the problem.

The latest Application Loader is as follows:
