Error when click on Imagery providers

[kudlav]

What steps will reproduce the problem?

1. Imagery -> Imagery Preferences
2. Imagery providers Tab
3. Available default entries
4. Click to any value in Menu Name or Imagery URL column
5. Almost on every item you will get an error (e.g. click on "Landsat", "Hike & Bike")

What is the expected result?

I have expected a least just selecting the row.

What happens instead?

Instead of selecting, it gives me an error: "An unexpected exception has occurred". I will attach the screenshot.

Please provide any additional information below. Attach a screenshot if possible.
