plasmashell reports lots of errors in distributed files

1. Run KDE and open a terminal (I used Konsole but I assume it doesn't matter).
2. Run following command

    plasmashell --replace &

Expected results:

Plasma shell (the bottom bar with clock and task switcher and system menu) should restart without side-effects.

Actual results:

Plasma shell restarts and a lot of errors are emitted to the console output:

I do software for living and if my software was emitting this kind of info, I'd assume it's pretty broken. The libpng warning is the only one that's probably caused by some other software (the software to create a broken PNG file, unfortunately the error message doesn't tell us which file it's processing) but rest of the output seems to be just KDE stuff.
