qlineargradient apply white color on production linux

[Donki]

Hello,

I have an application that use qwizard class to make a wizard. This is compiled with QT 4.8.6 tools.
This application runs over Fedora 18 with KDE, Fedora 18 without desktop and Debian 8.5 with gnome desktop and applies qlineargradient layout ok over this environment.

But when I execute this application over Debian 8.5 without desktop, it justs apply a white color where qlineargradient must be applied.

What can i do to solve this problem?

Thanks in advance.
