Yep that's the same issue.

Basically we have foo-1 provides bar and the new foo-2 doesn't.
And baz depends on bar.

While resolving dependencies, pacman believes that foo-1 satisfies the
dependency bar of baz and doesn't see that foo-1 will be upgraded to
foo-2 which no longer provides bar. (And since it believes the bar
dependency is already satisfied locally, it doesn't pull the new real
bar package)
When pacman later checks the dependencies, it finds the issue, but
it's too late and it just errors out with :
baz depends on bar

1) foo = qt
bar = phonon
baz = kdelibs

2) foo = kdepim-runtime
bar = kdepim-akonadiconsole
baz = kde-meta-kdepim
