Can't get Wuala to use the installed 32-bit Java in 64-bit Ubuntu Linux

Dear Wuala,

I am leaving Windows behind, and am going full-time over to 64-bits Linux.
I have run Wuala in nogui mode for a bit, but it is too limited. I.e. configuration is difficult/impossible and there is not much feedback from the application of what is going on.

So I want to get the gui going. But I am having troubles. I have installed 32-bit java alongside the 64-bit java that I have already installed. I have also set the JAVA-variable in the Wuala config file, but it doesn't work.

This is a quite fresh install of Kubuntu-64 8.10, all updated per today 17.Feb 2009.
Dual-core Intel Pentium D with 5 gigs of memory.

Can you help me out?

You are trying to start Wuala with GUI with 64-Bit Java, which is not yet supported.
Please try running Wuala in the commandline mode (-nogui) instead or try installing 32-Bit Java.
