I think type is wrong for watchdog

Someone had an earlier issue about the type being too big or so. I was getting a similar message.
I really don't know what I am doing, but I did realize that the watchdog for this module was placing "action_email_role" as the first string, where most other modules were using "action" or "error".
I placed "action" for the sent message watchdogs and the error went away.

I hope that helps towards a permanent solution for the author (or let me know if this was really not a help!).
Other than that this was just the module I needed. Thanks.
