Multicession craches with DVD+R and not with CDs

[Papy Octet]

Binary package hint: k3b

Hello,
Before installing Ubuntu 9.04, K3B runs very fine. But now - from Ubuntu 9.04 and Ubuntu 9.10, it impossible to write multi-cessions DVD+R.
I can write the DVD a first time but after, K3B seems starting multi cession burning but crashes immediately when burning at all the datas written on ce DVD are loosed !
I have tried all the settings possible, all the speed possible in K3B for my DC/DVD writer LG HL-DT-ST - DVDRAM GSA-H42N (this DVD writer worked fine before Ubuntu 9.04 and it run always fun under Windows Xp and Vista with NERO !) but it is always impossible to write milti cession.

When I try multi cessions on CD+R or CD-R, K3B runs fine in multicession.

I use DVDs from Philips, EMTEC, TDK usually.

A+
