Please don't set priority to high when reporting bugs, especially when they're not security-related. MacPorts developers will increase the priority if necessary.
When reporting bugs against ports, please fill in the port field.
When posting in trac, please preview your post and use WikiFormatting.
For the record, the problem is

The port should be updated to the current version, and if that doesn't fix the problem it should be reported upstream.
