I'm not sure what has caused this to be a problem for 3.7 it has barely been touched since 3.6.2.

In any case, I've attached a patch which includes a fix and modifies a test (well several to move a method into a super class) to catch this.

We had problems tagging for the build and the fix did not make it into the 3.7.1 build.  I'm not sure if a 3.7.2 build is planned, but the fix does is in the 4.2 and 3.8 builds.

The 'Version' field on this bug still states '3.7' however.

I am assuming that field indicates the version of the software the bug is fixed in? If it is indeed only fixed in 3.8 it may help to set that field to that value.

No, it means the bug was found in that version. It may be in an older version too, but at least someone has found it in that version anyway.
