Bug Description

Thanks to bad event timing during the size calculation the folderview widget has a very small size when added to the desktop instead of the recommended size. This makes it unusable unless you manually resize it.
We use the folderview widget to display the installer icon on the live image, which makes the installer almost invisible as you can see on the screenshot.

[Test Case]
This can be tested on any installed system and doesn't require an updated image.
- Try adding a folderview widget to your desktop by right clicking on the desktop -> Add Widgets -> select Folder View from the list.
- it will have a very small size and usually show part of an icon (see attached screenshot)
- install libkf5plasma5 and libkf5plasmaquick5 from proposed
- restart plasma using Alt+F2 and running 'kquitapp plasmashell; plasmashell'
or by restarting your login session.
- Try adding a folderview widget again using above steps
- it should now be large enough to show 2 rows, 3 columns of icons.

[Regression potential]
The patch has been recommended by upstream, has not caused any direct regressions and no misbehaving widgets have been found by just adding this patch.

[Original Description]
Description: Ubutnu Xenial Xerus (development branch)
Release: 16.04

Installed: 1:16.04ubuntu2
Candidate: 1:16.04ubuntu2

I we run live session either from USB or in virtual machine then the default Folder View widget with installation icon inside is rendered in small size, making the mentioned icon almost invisible (see attached screenshot). This widget size should be changed to make the whole icon inside visible.

if i add a Folder View widget to the desktop in an installed Kubuntu, it has the same small size. i don't know what defines the default size of a new Folder View widget, whether it's a config parameter or a line of code, but i guess that's where the root cause of the problem is.

Ok, after looking into this I was pointed to and after a quick test does seem to fix this. I'll try to get the SRU done ASAP.
