Details of the machine (MacMini4.1) etc appear in the report itself. In short it has a 2.4 GHz Intel Core 2 Duo processor and 2 GB of 1067 MHz DDR3 memory. The boot hard disk is the internal 320 GB disk. I have just seen that the graphics card is NVIDIA, and I have seen a number of reports about panics with that type of card. The only external devices are a 250 GB LaCie disk which I use for Time Machine backups and a Brother HL-5340D laser printer. Oh, and there is an external dvd drive which I occasionally use for burning (but not since upgrading to Lion).
The problem most often occurs when I am on the internet, either with Safari or, as in the last three cases, with the App app. I have been trying to download Lion again in order to be able to create a Lion bootable installation disk. Each time the panic has occurred in less than 10-15 minutes.
I'm very grateful if you can interpret the log - I have several others I can send if necessary - and help me to a solution.
Here is the panic log:
