unmerge gives weird errors

[Guest]

when i try to unmerge some gnome stuff, I get this:

bash-2.05a# emerge unmerge gnome-extra
Traceback (most recent call last):
File "/usr/bin/emerge", line 1179, in ?
unmerge(myaction, myfiles)
File "/usr/bin/emerge", line 674, in unmerge
mymatches=localtree.dep_match(x)
File "/usr/lib/python2.2/site-packages/portage.py", line 2230, in dep_match
if not self.hasnode(mypkgdep):
File "/usr/lib/python2.2/site-packages/portage.py", line 1804, in hasnode
myreskey=self.resolve_key(mykey)
File "/usr/lib/python2.2/site-packages/portage.py", line 1753, in resolve_key
self.load(mykey)
File "/usr/lib/python2.2/site-packages/portage.py", line 2252, in load
mycat,mypkg=string.split(mykey,"/")
ValueError: unpack list of wrong size

a) what's wrong?
b) how do I uninstall stuff if unmerge fails?

same error here
can't understand this one, it's a fresh 1.11a install, gnome, mozilla & opera emerged, and when i try to unmerge opera i get almost the same error.
does anybody else have the same prob?
