In 1978, M. Kashiwara and M. Vergne conjectured some property on the Campbell-Hausdorff series in such way that a trace formula is satisfied. They proposed an explicit solution in the case of solvable Lie algebras. In this note, we prove that this {\it solvable solution} is not universal. Our method is based on computer calculation. Furthermore our programs prove up to degree 16, Drinfeld's Lie algebra ${\frak grt}_1$ coincides with the Lie algebra $\widehat{{\frak kv}_2}$ defined in A. Alekseev and C. Torossian: The Kashiwara-Vergne conjecture and Drinfeld's associators, arXiv: 0802.4300.
