Concealment crash due to invalid characters

I have been getting the following errors on my server:

I happen to have a few Russian players, and they have named their ships with Russian characters. Is that the causes of these errors, or just a strange coincidence. The errors usually happen exactly 30 minutes after they log off the server.
