Not all images have metadata, data should be checked first

[trusktr]

I'm getting many errors like these. Is this a problem with a plugin, or with WordPress core?

The errors seems to be happening in core files, so I thought I'd post it here.

To see the actual errors, see the following site (at the time of this writing), in the right sidebar (scroll down):

I need more information then this. Seems like the image metadata is corrupted but no clue why and what. Seems like a plugin is doing something wrong but hard to tell.

The plugin that generates the sidebar widget where the errors show up is eshop, but the error doesn't point to any files from the eshop plugin.

If you look at the code you see that the error isn't on that place. The data from wp_get_attachment_metadata() isn't how it should. Maybe a plugin does something wrong or you did a replace query on urls. However last one would most likely not show these errors.
