git svn clone with funky tags layout

I'm doing a one-time migration of an svn project.  For historical reasons our repo layout is weird:

    trunk/reporting/reporting_app

    tags/something_else
    ....
    tags/reporting_app-2.3.45
    tags/reporting_app-2.4.46
    tags/reporting_app-2.4.0
    tags/reporting_app-2.4.1
    ....
    tags/more_stuff

I want to migrate the trunk plus only the 2.4.* tags.  I tried giving a wildcard in the config

[svn-remote "svn"]
        noMetadata = 1
        url = http://subversion.tld.com/svn/DevJava
        fetch = trunk/Reporting/reporting_app:refs/remotes/trunk
        tags = tags/reporting_app-2.4.*:refs/remotes/tags/*

but this does not work:

    Invalid pattern in 'tags/reporting_app-2.4.*': reporting_app-2.4.*

On the off chance that it might work I also tried

            tags = tags/reporting_app-2.4.*:refs/remotes/tags/reporting_app-2.4.*

but that produces the same error message.

Is there a way to accomplish this or should I just move the tags I want to import into a separate directory in subversion first?  I'd rather not disturb svn but can do that if it's the only way.
