Hi,

I have a serious problem since Tackat commited a load of icons yesterday.
All programs that use icons like
/kdelibs/pics/locolor/lo16-action-2rightarrow.png
crash with a backtrace like this one: 

Program received signal SIGSEGV, Segmentation fault.
chunk_alloc (ar_ptr=0x412891a0, nb=72) at malloc.c:2814
2814    malloc.c: No such file or directory.

#12 0x405b5590 in KAction::KAction () from /opt/kde/lib/libkdeui.so.3  

file output for these icons:
lo16-action-2leftarrow.png: PNG image data, 16 x 16, 1-bit colormap, non-interlaced

The crash only happens when "Semi-transparent" is used as icon effect for
disabled icons.

I use a clean rebuild of qt-copy/kdelibs/kdebase and tested -qt-libpng and
-system-libpng (2.1.0, SuSE 6.4), makes no difference.
