Recurring message - Font 'Times Arial' has not been found using 'Times New Roman' font instead

In one of the logs for Collaborator, I see recurring messages that say

Font 'Times Arial' has not been found using 'Times New Roman' font instead

followed by some related info about font substitution and how you should install the missing font to prevent this message from occurring.

As far as I know there is no available font named 'Times Arial'.

Does anyone know how to track down the cause of this recurring message?

Thanks in advance.
