Comment (by cutsea):

 Thanks for your replys.

 > Cutsea, have you been able to reproduce this after cleaning your source
 tree?

 I can reproduce this by following:
 {{{
 $ mkdir sandbox
 $ cd sandbox
 $ cabal sandbox init
 $ cabal install metadata
 }}}

 By the way, my environment after occuring panic is:

 {{{

 And my ghc is installed by using apt-get(debian package).
