Version:           2.2.0 (using KDE 4.7.2) 
OS:                Linux

After an update to libpng digiKam does not display any images in the imported albums. When I start digiKam from the terminal, I get the following error: 

libpng warning: Ignoring extra png_start_read_image() call; row buffer not reallocated 

Then digiKam starts, show the directory tree, where I have my photos but shows that I have zero photos in each directory. I tried recompiling digiKam and kipi-plugins, but that did not help. Also ran revdep-rebuild. Finally, I tried recreating database of images in Digikam and that did not help either. Currently I have libpng 1.5.5 and 1.2.46 installed. Any help would be appreciated! 

My emerge --info is:
