ERROR: "A Group in the backup file is missing the groupName parameter." upon project import

Question

When trying to import a project from an XML dump, we receive the following error:

{code}

There was a problem parsing the backup XML file at /home/jira/atlassian/jira-home/import/one.zip: A Group in the backup file is missing the groupName parameter.

{code}

Both the source and target instances are using v5.0.3#729

Found the problem! Open up the zip file, and edit entities.xml then search for groupName. In my case, I have a blank group name like below:

Add values to groupName and lowerGroupName (eg. "unused"), create "unused" group in JIRA, and import the project
