Too large profile pictures don't trigger an error message

Version: 6.1.0-alpha.5 (but it's probably an issue we had from the start.

Too large profile pictures don't trigger an error message.

When the user attempts to add a profile picture that is significantly too large (e.g., 1.5 MB), the error message indicating that the image is too large does not appear. The image is not added, but there is no explanation for the user. It's because using a photo that's too large crashes the socket transport when trying to transport the base64 encoding.
