i recently did a emerge-websync a few days ago and went to update world and system. 'emerge -u system' crashed with the same bug but it was fixed when i did 'emerge --metadata'. after this the problem still remained for 'emerge -u world', so i tried 'emerge --regen' but no luck either. i also updated my portage tree a few days later but still nothing.

For the time being, rm /var/cache/edb/dep/*-eclass.cpickle will fix it. Or if you feel really adventurous, it would be great if you could track down which of those files is causing the problem and attach it. You can do so by: 1. Find line 4354 that matches the second last line of code in the traceback 2. Insert a line before it, indent to the same level using tabs and add "print cat" 3. Attach the eclass pickly for the last category printed before the traceback.
after adding 'print cat' to file, the last catagory printed was dev-perl, it appears that this file has nothing in it, and hence was not allowed to be attached. the file is dev-perl-eclass.cpickle. i guess this file is suppose to have something contained in it? why would it suddenly become empty? is it safe to delete?
portage-2.0.50-r11
To fix it for the time being: rm -r $(find /var/cache/edb/dep -name dev-perl)
that fix did not fix the problem. if i run 'emerge -u world' again with the 'print cat' in there the traceback still stops at dev-perl.
Bug has been fixed and released in stable portages on or before 2.0.51-r2
