No, only guessing. Except that type="float32" is plain wrong, it
should be "float32[]"

Another possibility is that this is a typekit ordering problem, which
we fixed in Toolchain 2.6, and can't backport to 2.5. Just make sure
that your dependencies and ros package paths are in the same order all
the time in order to avoid such conflicts.
