minor(?) problem with pkg crashing

[Andriy Gapon]

pkg 1.7.2 crashed at the end of upgrade run, after completing all the upgrades.
Unfortunately no debug symbols, but it looks like a double free or something
like that, seems that this happens only if
> Conflicts with the existing packages have been found.
> One more solver iteration is needed to resolve them.

The crash is in  pkg_jobs_free() -> pkg_free() -> free()
