Comment 6 for bug 619003

Strange thing happened here during Lucid to Maverick upgrade.

Hardware: Asus eeepc 1005PE hooked to a Hyundai external monitor res 1440x900 and a Logitech external usb mouse/keyboard

At the middle of the upgrade, the machine started to be very slow, let's say about 10 to 20 times (or more) slower to perform the upgrade statements, cpu load constantly very high.
The mouse was moving very slowly by steps, and all interactions were completely slowed down.

After a while during upgrade, I disconnected the external monitor and mouse/kbd, and set the display back to netbook's with keys Fn F7, and it went back to a normal update speed until the end (upgrade seems OK).

Looking at the /var/log/dist-upgrade/apt-term.log after upgrading, I can see 8322 (out of 22221 total) lines containing:

(gtk-update-icon-cache:nnnnn): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file '/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache': Aucun fichier ou dossier de ce type

These statements appear by packs of ~70 lines, regularly in the file.

Is there some relation here between those events, and is it necessary to perform the upgrade without connecting external devices like a monitor ?
