  The behavior of several nuclear properties with temperature is analyzed
within the framework of the Finite Temperature Hartree-Fock-Bogoliubov (FTHFB)
theory with the Gogny force and large configuration spaces. Thermal shape
fluctuations in the quadrupole degree of freedom, around the mean field
solution, are taken into account with the Landau prescription. As
representative examples the nuclei $^{164}$Er, $^{152}$Dy and $^{192}$Hg are
studied. Numerical results for the superfluid to normal and deformed to
spherical shape transitions are presented. We found a substantial effect of the
fluctuations on the average value of several observables. In particular, we get
a decrease in the critical temperature ($T_c$) for the shape transition as
compared with the plain FTHFB prediction as well as a washing out of the shape
transition signatures. The new values of $T_c$ are closer to the ones found in
Strutinsky calculations and with the Pairing Plus Quadrupole model Hamiltonian.
