Error when sorting the modifications by creation date.

[Carlos_N]

What steps will reproduce the problem?

1. With the MY MODIFICATIONS window open, if I click on the top of the creation date column to sort the items, the error screen comes up.

If I sort by any other field, it works fine.

What is the expected result?

What happens instead?

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