Comment 3 for bug 815905

Yes, I'm pretty certain this is a duplicate of bug #168914, and it should already be fixed in Ubuntu Oneiric. In the meantime, you could try installing the latest development version of the libgc package.

I'll mark this as a duplicate, but please feel free to revert the change if you find that the bug can be reproduced when libgc >= 7.1 is installed.
