Version:           2.4-snapshots (using Devel) 
OS:                Linux

UBUNTU 11.10 - 64 bit (Oneiric Ocelot) - UNITY SHELL
Kde 4.7.41
KRITA 2.4 - beta 3 (installed through ppa:neon/ppa)
Vbox 4.1.4 (Windows 7 as Host; Ubuntu is the guest)

My Distro is updated - upgraded daily (so it is the ppa:neon/ppa package)

Reproducible: Always

Steps to Reproduce:
1. Take a screenshot of your desktop before opening Krita 2.4 (b3) and save it as png;
2. Fire up Krita and open up this png screenshot;
3. Go to Layer -> Edit Metadata;
4. On the first Tab (Exposure), write something silly (e.g. 22222) inside the Brigthness value line. Press ok to confirm;
Now here comes the trick to Crash Krita (and *many* other open source software: e.g. previous versions of Darktable...).
5. Save these changes: ctr+s  (I know they are crazy for a screenshot but....);
6. Krita crashes silently (probably it doesn't expect these sillines in the png Metadata).
Dr Konqui doesn't start: it is the perfect murder... :-) 

Pay attention, in order to get a backtrace you are forced to start Krita 2.4 through the Gdb debugger

After this crash Krita is unable to open this screenshot.
When you try to open there is this message error:
Could not open
/home/silvio/Scrivania/screenshot.png.
Reason: Parsing error

Actual Results:  
Krita crashes and destroy your png screenshot forever :-)
Not even Gimp 2.7.4 can open and restore it afterwards :-)

Expected Results:  
Krita shouldn't crash.
Most of all, Krita should NOT allow you to edit screenshots metadata!

Here is the last part of my backtrace (the very first part is not available on my Terminal: it has been cut because it was too long)
