Failed to load image '/usr/share/nux/1.0/UITextures/...': Icon has zero width

Getting a couple of errors like the following upon session start:

ERROR 2011-08-06 17:57:37 nux.image GdkGraphics.cpp:68 Failed to load image '/usr/share/nux/1.0/UITextures/Stroke_10pxrad_2px.tga': Icon has zero width
WARN 2011-08-06 17:57:37 nux.image GdkGraphics.cpp:80 No pixbuf loaded

All those files exist and have width > 0.
