There are stacks of the main SciLab process and childrens

SciLab hangs trying to plot after upgrading to Ubuntu 10.10
The simple way to reproduce a bug is typing in SciLab console:
plot([1,2,3],[4,5,6])
After this I see a group org-scilab-modules-co... with 3 elements:
[SciLab console] - not responding
Java - no window
[Graphic window number 0] - gray, not responding
But I wait for a plot with a single line y=x+3.
I try Xorg-Edgers Driver without any result.
I try VirtualBox with Ubuntu 11.04 but plot works normally until installing
VirtualBox Guest Additions. After installing Additions the program closes
trying to plot.
I try VirtualBox with Windows Server 2003 R2 official Microsoft trial VHD
virtual disk. The plot command works.
I try different versions of SciLab including Nightly Build (last unstable version) with the same
result. But Nightly Build stay UNKILLABLE after plot command.
All other programs work normally.
I try to comment a bug 3843 (http://bugzilla.scilab.org/show_bug.cgi?id=3843) but the answer is: incorrect graphics holding in new UBUNTU version.
So, I also report it to https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/886029
Please help me.
