There *is* a [B]/usr/lib32/libgio[/B] and there *is* a [B]/usr/lib32/libcanberra[/B] on my system. 

The library search path seems broken. 

I'm in the no-rush-to-Unity camp, so if an upgrade is suggested, it will probably be Mint or the rolling Debian Mint.

On closer examination, my installation gives exactly the same errors. However, the product runs normally and I have found no problems.

It looks like a bug in Ubuntu that affects many 32-bit apps. If you are interested, search for
/usr/lib/gio/modules/libgvfsdbus.so: wrong ELF class: ELFCLASS64

I had a previous xpresso from about a year ago installed under [B]/usr/local/LPCXpresso[/B], and I had done the path manipulation:

/home/allan/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/LPCXpresso/bin:/usr/local/LPCXpresso/tools/bin

When I ran into problems with the fresh install, I renamed the old install directory and symlinked [B]/usr/local/LPCXpresso[/B] to the new installation directory. 

How does strace show the problem libraries loading on the fresh install?  As per my original post on this box you can clearly see it looking not in the right place.

It works here. To validate I just did a completely clean install of Ubuntu 10.10 64-bit.

Did you follow the instructions that tell you to:

sudo apt-get install linux32 ia32-libs 

on 64-bit installations?
