bug#20817: 25.0.50; Problems with upgrading of packages

[Mark Karpov]

***

It seems like there are some problems with upgrading of packages
now. When I call ‘package-list-packages’ command, the list is printed,
but I'm also presented with a message in the minibuffer that reads:

  error in process filter: wrong type argument: listp, :error

When I want to upgrade some packages, I get this error message instead:

  Package `...package description...` is unavailable

It's strange, I guess it's some sort of bug.
