Really? Was it encrypted? If so, did you put the passphrase in pywallet? 
Topic: Finding out which wallet addresses have a non-zero balance (Read 3365 times)
By the way, in the meantime I've managed to solve my problem. Here's how:
Step 3 was key: initially I tried importing also using pywallet. However, Bitcoin-qt was then unable to read the wallet. The solution was to use bitcoind itself to import the private keys!
- Used "pywallet --dumpwallet" on my backed-up wallet to get a list of private keys.
- Deleted the wallet and started Bitcoin-qt. This created a fresh wallet.
- Wrote a shell script to iterate through all the old private keys and import them using "bitcoind importprivkey account rescan=false"
- Restarted Bitcoin-qt with rescan option

1. pywallet does this with the '--dumpwithbalance' flag (takes ~2 min / 100 addresses, of course depending on your connection)
Which version of pywallet does this? I got mine from Github yesterday, and it does not have this option!
It does have this option, I just checked. Please check with 'python pywallet.py --help'
2. why don't you just import the wallet.dat in another bitcoin-qt installation?
Because frankly, the mess with Bitcoin in Ubuntu is such (because of the differing libdb versions) that a different installation will crash on start up if I give it my wallet backup. I've tried.
You do not need to do all this.
When you have backup of wallet.dat - you can just put it into bitcoin-qt corresponding folder (after you will manage to get it to work again).
Or else, you can create online wallet and import your wallet.dat backup there https://blockchain.info/wallet/import-wallet

I appreciate the reply, but did you read my question carefully? The problem is that after the upgrade, Bitcoin-qt will crash on start up if I give it my wallet backup! This is of course because of the differing libdb versions problem which has plagued Bitcoin-qt on Ubuntu for a while now.
However, importing the wallet into an online provider is a good option. I'll keep that in mind.
But, if all you want is just know balance -
1) create new wallet using pywallet
2) import all addresses and private kyes
3) open this wallet using bitcoin-qt
4) goto help-debug window-console (this is on Windows, but I suppose on Linux it is the same)
5) write command getreceivedbyaddress XXXXXXXXXXXXXXXX(insert address here)
If address is not in your wallet - you will not be able to see balance on it
1) create new wallet using pywallet
2) import all addresses and private kyes
3) open this wallet using bitcoin-qt
4) goto help-debug window-console (this is on Windows, but I suppose on Linux it is the same)
5) write command getreceivedbyaddress XXXXXXXXXXXXXXXX(insert address here)
If address is not in your wallet - you will not be able to see balance on it
So basically I have to create a small script anyway to automate this process. Which is what I why trying to avoid...

I'm unable to start bitcoind/bitcoin-qt after the latest upgrade of the Ubuntu PPA. However, I've got a backed-up wallet.dat, and using the pywallet utility I also have a list of addresses and private keys. I think the best solution right now is to create a new wallet and to import into it the one address which does have an associated balance (I know there is only one). However, I don't know which address it is! Is there a way to find out the balance associated with each address without having to manually check them on the Block Explorer? (And yes, I could write a small programme to automate this process, but it seems I would be reinventing the wheel and abusing the Block Explorer service).
