[Solved] Black Screen after KDM - plasma-desktop error with libpng

Hey,

i just wanted to log in to my arch session, but after KDM theres just a black screen.
I found out, that all programs startet via krunner are working.
So it's just plasma-desktop, what makes the problems

plasme-desktop
LONG OUTPUT AND IN THE END
libpng warning: IDAT CRC error
lippng error: PNG unsigned integer out of range 

thats it... plasma-netbook works without any problems... also window effects are working

Dont know wheter its any help, but i dualboot with macOS and share the desktop, where 2 .jpgs are stored, dont know wether this is important...

Edit:
I've tried to delet the jpgs in the desktop folder and uninstalled kde-wallpapers. Still no luck
I've also tried to downgrade libpng to 1.5.14, but when i reboot, kdm wont start.... maybe there's something i haven't thought through....

However the Output changed a bit, heres the full output:

[markus@MacBook ~]$ plasma-desktop

Re: [Solved] Black Screen after KDM - plasma-desktop error with libpng

Should have done that earlier... renaming .kde4
Now it workes... and after uninstalling yawp-plasmoid i renamed .kde4... everything's fine now!

So if anybody else runs in this problem too, my advice: check your aur-plasmoids!
