Comment 16 for bug 1217757

I have experienced this kind of slowing down when opening Synaptic.
Opening Synaptic is delayed about 10 sec. It will open finally, however.
I traced the bug to the package at-spi2-core (libatspi2.0-0 version 2.9.90-0ubuntu1)
and possibly also to at-spi2-atk (libatk-bridge2.0-0 version 2.9.90-0ubuntu1).

After downgrading the packages back to the previous ones (versions 2.9.5-1ubuntu1 and 2.9.5-1) all is well and Synaptic opens immediately without any delay.

I use the old d-bus (version 1.6.12-0ubuntu2) for the time being.
I haven't tried the latest version 1.6.12-0ubuntu5 depending on libapparmor1 yet.

I have a 64-bit setup with only Gnome-Shell DE.
