Bug 363127

First of all I would like to say that currently I am testing Krita for different projects of mine (painting animation frames, image editing etc) as I'm thinking about switching to Linux for my main work computer. Currently I'm in Windows and my system specs are:

Windows 7 SP1
32 bit system
Intel Core Duo 2.26 GH
3GB Ram
ATI Radeon GPU

Here is the link to download a ZIP with a typical .kra file that I'm working with (please note that it's 34.4 MB)
https://dl.dropboxusercontent.com/u/55690400/DSC05434.zip

In the file there are 3 filter layers that I drag to other images so that I have the same color adjustments in a group of pack-shots.

The images I work with are high resolution (2048 X 3072 pixels)

First I hide the visibility of said layers and then I drag them (while holding down Shift) to another file. This usually causes Krita to become unresponsive for about 15 seconds and then the layers are in the other file. However other times (and that's often) Krita simply crashes. Note that I always have instant preview turned off (since it causes an outright crash). I have tested this with both OpenGL enabled and disabled and it happens anyway.

Also I have enabled the option in the settings for Krita to capture a log file but when I look in said directory there is nothing there (that's why I'm sending you the .kra file)

This is a typical workflow for me when I am editing pack-shots and when I work with files like the one I am sending you sometimes things generally get very slow and I get frequent crashes. I do not have these problems when a file does not have Filter layers or when I am just painting.

I know that Krita is positioned as a drawing app but since it has image editing features perhaps they should work a bit better, especially since the UI is so much better than Gimp 2.8.

Also I've been looking for Krita's system requirements and I couldn't find any. My system is old (obviously) and I don't know how Krita performs with Filter layers in Linux (I hope that it's better than what I experience currently).

Maybe an improvement of Filter layers or dragging layers between files should be a future feature...

Reproducible: Sometimes

Steps to Reproduce:
1.Hide visibility of 3 Filter layers
2.Select them
3.Drag them to another file
