That's what I thought for three hours of resetting, rebooting and looking 
for the problem everywhere but in the toolchain.  I am sure of my report 
because this is what I did after those three fruitless hours:

1 - Reinstall Windows XP SP3 (actually, overwrite the partition with a 
snapshot taken at the second reboot of a Windows installation, which is the 
same thing but a lot faster)
2 - Before installing anything, other than Firefox, install AVR Studio 4.19 
and the Jungo USB drivers.
3 - Install AVR Toolchain 3.4.0.
4 - Perform four trials using two projects, one new and one known to be 
problem-free, and two debug interfaces, an AVR Dragon and a JTAGICE Mk II. 
AVR Studio crashes at Start Debug on all trials.  Reboot the PC between 
trials.  On all trials, Connect To Debugger and Read Device Signature worked 
fine.  I used Update Firmware on the AVR Dragon.
5 - Uninstall AVR Toolchain 3.4.0.
6 - Install AVR Toolchain 3.3.1.
7 - All trials now enter debug successfully.

I don't have the time to be interested right now.  If my guess that Atmel 
are dropping support for AVR Studio 4.x is correct, then they won't be very 
motivated to figure this problem out.
