Too bad bitcoin-qt can't use your GPU to accelerate re-indexing the block chain. It's already using multiple CPU cores if they're available.
I don't think GPUs lend themselves to ECDSA validation very well. It's an interesting idea, though.

can you remember the smell of paper tape?
I remember handing stacks of IBM punch cards through a window to a computer operator in the inner sanctum.
Each card contained one line of Fortran IV source code.
Software wasn't for woosies back then.
Remember when software was purchased as source code printed out in magazines and you had to key it all in to use it?
Sometimes they would just publish the binary, as a hex dump, and you had to type in the hex characters. That was really painful. At least while typing in source code you could get an idea of what was going on. But hex just looks like hex...

Remember when Computer Shopper used to be the size of a phone book in a major metro area?

The workaround is sudo apt-get install kubuntu-desktop.
xubuntu-desktop or lubuntu-desktop will work too.

I'm running Ubuntu 12.04, all upgrades applied, in a VirtualBox. Almost all networking is IPv6. The VirtualBox has 512 MB (<--small, I know) RAM.
The host machine is a dell Optiplex GX620, XP-SP3, 4 GB ram, 3.00 GHz pentium 4

Congrats on running a 11 month old OS, on a 11 year old OS on a 10 years old computer (P4 3.0GHz release April 2003). There weren't many people trying to use a 1991 computer (pre CD-ROM) in 2001 (post-Google).
Is this progress or a lack of progress?
I'm running Ubuntu 12.04,
One thing I notice is that the menu (File, Help, & such) does not seem to display if the program is shut down, and then restarted. If the window is maximized, these items show up again.

You are not the first to report strangeness with Unity (the bastard pile of MacOS wannabe move-the-menu-to-the-top bs that Ubuntu slapped on Gnome in order to keep up with Windows 8 in the stupidifying of GUIs). There is an official issue here: https://github.com/bitcoin/bitcoin/issues/1242 where you can add your steps to replicate on 0.8.0.
The workaround is sudo apt-get install kubuntu-desktop.

I created a new virtual machine, created a disk specifically for bitcoin, and mounted it on ~/.bitcoin. I used ssh to copy the ~/.bitcoin directory over from the 0.7 installation.
My bitcoin.conf file includes
connect=
onlynet=IPv6
logtimestamps=1
server=1
At startup, 0.8 seemed to index about 10-15 blocks / second. I started it mid-day and the projections were that it would finish by 8PM last night.
At about 6AM this morning, it was still about 2,000 blocks from being indexed. The speed had slowed to about 10-12 seconds / block.
With block 223,261 now onboard and everything current, and after erasing the old blockindex.dat file, du . shows 6,842,184 bytes. This includes some logfiles that include timestamps.

I agree with Mike Hearn that this is likely the cause. The PC I had this problem with is a 5 year old laptop which just might be breaking down slowly but surely. It's not a problematic PC otherwise but I guess LevelDB is intensive enough to be problematic if there is even a small flaw with the HD.
Maybe I need a new laptop.
Or take it apart and clean out five years worth of lint and fuzz and put new thermal compound on the CPU cooler:Maybe I need a new laptop.
After finally absolutely having to upgrade from my oldschool 0.3.16 or something version, I have to say this is looking way more polished. Nice work all around

Or just a new drive for it.

Re-indexing the block chain is unusually intensive. If there are minor faults being introduced by your HDD then most apps probably wouldn't detect them for a long time but Bitcoin is very sensitive to it. If it's not hardware related why are you seeing signature check failures (can only be caused by bad hardware, pretty much) and other machines are working fine?
That sounds a lot like some kind of hardware failure.
On two machines ? Very unlike.

Reindexing helps me getting closer to the end of the chain. But it's slow as hell 
One step forward, two steps back.
Edit: going back to 0.7.2. Hope future releases take care of this problem.

What is causing this ? I'm having a hard time to get 0.8.0 up to date. Win7 32. 2 PCs, same troubles. 0.7.2 was working flawless.

0.8.0 is great. Thanks to all the developers!!
Much faster when catching up with the blockchain.
