I received this message after upgrading to 2.11.0 and adding a custom logo. The image failed to validate with pngcheck. It must have gotten corrupted during conversion. Uploading random files with non-.png suffixes did not produce the error. I labeled a .jpg with .png and produced the error.

Verifying the image was a valid PNG fixed any issue.

Putting the .png suffix on a text file generated other errors.

Thanks @palleroy0 for the suggestion, we could improve the messaging to make it clear to user that the image had an invalid format.
