3.2.1 crash in Kde4

Hi to all.
As I write in the subject every time I open a file dialog in ooo3.2.1
I got a crash.
The error I got is :

X-Error: RenderBadPicture (invalid Picture parameter)
        Major opcode: 147
        Minor opcode: 8
        Resource ID:  0x6400fe0
        Serial No:    45416 (45416)
The crash occours in a time variable from instantly to 10-15 seconds
apparently in a random way.
It seem it occours faster if I activate the preview function in the
dialog or if the directory showed is with a lot of files. I've test
the error on 5 different machines.
The distro is openmamba with kde 4.4.4
If I switch the dialog from system ones to openoffice all works well.
Any clue ?
