I tried to import all issues from a Redmine installation. The installation uses a group to assign issues to that group. The import process failed with the following error:
2013-01-08 12:10:01,180 ERROR - Unexpected failure occurred. Importer will stop immediately. Data maybe in an unstable state

The importer requested /users/8.json?include=memberships which does not exist:
x.x.x.x - - [08/Jan/2013:12:10:01 +0100] "GET /users/8.json?include=memberships HTTP/1.1" 404 616 "-" "-"
Redmine user with id 8 is not an actual user, but the above-mentioned group. Therefore, the above request fails (not found). As a workaround, I created a new dummy user with id 12, that does not belong to any group or project, and set up the following redirect:
RewriteRule ^users/8\.json /users/12.json [L,R]
That way, the importer got the return value for user with id 12 instead. I assume this is a bug in the Redmine importer plugin, isn't it?
