Salesforce developer orgs do not have the ability to open cases with their support team.
I've known people who registered as consulting partners under their own personal name to get access to partner support, but I have no idea if that's something that's frowned upon by salesforce or not.
The developer forums are also supposedly monitored by salesforce support staff but I have no idea how effective this is.
If you have a production org you can use for logging a case, do so (unless you're a partner, then use the partner portal). If not, you can try other options.
After looking around looks like you cannot open a case from DEV orgs anymore. Trying to find documented proof, will attach with this answer as soon I find it.
