Nice day!

This sounds weird. Yesterday I built the PKGBUILD and Tomahawk run flawlessly. Here the code:

# Maintainer: Evgeniy Alekseev <arcanis at archlinux dot org>

  patch -p0 -i "arch-build.patch"

        "../${_pkgname}-${pkgver}"
  make
}

package() {
  cd "build"
  make DESTDIR="${pkgdir}" install
}

Take a look on this:

sed -i '373iif ( !m_model ) return;' tomahawk-0.8.4/src/libtomahawk/playlist/TrackView.cpp

I hope be helpful.

Best regards.
