Saw something interesting in the konsole window - just before the freeze

cable internet is out so I'm using 3G (USB tethering from the mobile
phone), which in our house is slow and gets an intermittent signal.

My theory is it looks like the Pyweather widget is hanging trying to get
data sometimes, and this in turn hangs plasma-desktop. Which, if true,
is IMHO a huge design fault in plasma-desktop. Anyway I'll see if this
theory holds out, Pyweather's been removed and so far no freezes.

Yes, that's the problem with plasma-desktoüp, it's single threaded, and
if one plasmoid hangs, whole plasma hangs. I often had such trouble when
using plasmoids I downloaded fron the net.

I also believe it's a huge design fault, but there _are_ indeed reasons
for doing this, having to do with speed mainly I think. I don't find the
link right now where this was explained, but if you are interested, I
could search and find it.

Retrieving data could still be done asynchronously, KDE's networking can do
that even in a single threaded application.

Looks like the respective applet or whatever it is using for downloading data
is broken.

Kevin
