Hi
After trying to open a jpg file, gimp, gwenview and I dont know what else, I cannot open any jpg file with these apps. I can open the images from other computer and from other apps like firefox, but not with gimp, gwenview.
I tried to restart everything, reinstall kio-extras, reinstall gimp, with no luck.
I tried to find a way to install plasma, but, the way google become is impossible to find good instructions. 
Any help will be most welcome.
Alex
