Comment (by simonmar):

 Replying to [comment:19 dons]:

 Ok, in GHC 6.8.1 and Cabal 1.2 we added various measures to prevent
 accidental mismatches such as this.  I need to establish whether these
 measures are not working for some reason, or whether you're running into
 cases that we just don't catch yet (there are definitely such cases, but
 hopefully much fewer than before).

 Please could you describe exactly the sequence of events that leads to the
 crash?

 To be clear: I believe all compile-time errors can be avoided by bumping
 versions when APIs change.  If you have evidence to the contrary, I need
 to hear about it.
