Some more info:

I added more error checks / output to vdr-burn (see attachment), and it
seems my imlib2 1.2.0 cannot load nor save png's when used from inside
vdr-burn.  It works fine when used elsewhere, and I can't see anything
obviously wrong with the vdr-burn code.  Beats me.

Oh, and the good news: downgrading imlib2 to 1.1.2 fixes it for me.
