Recently, I've been noticing that certain notification emails sent by JIRA have a subject, but the body of the email is completely blank. Only certain emails have this issue: Opening and closing a case is problematic, but commenting or re-assigning is not. Basically, if the prefix of the email is not [JIRA], we have a problem. Could this be an issue with a listener, or could a script have failed somewhere?
I am using JIRA 4.1.1
