This leads to a crash:

Indeed, the function arguments expected are different from what we passed. Looking at the introspection, there are two definitions of InstallPackageNames, one on org.freedesktop.PackageKit and one on org.freedesktop.PackageKit.Modify:

  <interface name="org.freedesktop.PackageKit.Modify">
    <method name="InstallPackageNames">
      <arg name="xid" type="u" direction="in"/>
      <arg name="packages" type="as" direction="in"/>
      <arg name="interaction" type="s" direction="in"/>


  <interface name="org.freedesktop.PackageKit">
    <method name="InstallPackageNames">
      <arg name="xid" type="u" direction="in"/>
      <arg name="timestamp" type="u" direction="in"/>
      <arg name="package_names" type="as" direction="in"/>

The actual implementation of the older implementation was commented out in commit 00dabc0477d036f84015f1627d1304daca5dcea5.
