Attached traceback automatically from anaconda.
1. Install from rawhide 20090420 boot.iso.
2. Keep all the defaults and keep clicking Okay/Next until you get to the screen where you can add more repositories, change packages etc. This screen should be right after writing the disk layout and enabling the network card.
3. Click "Back". A dialogue box appears stating that the file system has already been activated, so you can't go back.
4. Click "Continue". An unhandled exception occurs. Traceback is above.
Anaconda should have continued back to the screen where you can add more repositories, change packages, etc.
This will be fixed in the next build of anaconda. Thanks for the bug report.
