When recording, Rockbox is unable to update the Xing header with the
seek point table (the TOC). Therefore it generates a Xing header
containing the length, size etc, but without a TOC. The TOC can be added
using the "Update VBR file" in the ON+Play menu, or with a PC tool, for
example VBRFix.

This is news to me. Can you provide some files for analysis?

See above.
