Whenever I display certain images using display (from imagemagick-6.3.0.5), kwin (from kwin-3.5.5-r2) crashes. I'll attach a sample image. Here is the traceback: Using host libthread_db library "/lib/libthread_db.so.1".

Created attachment 107746 [details] Image causing the crash I got this image from a firefox theme. It is not the only image causing the crash, but it has the advantage of being small.
What libpng version do you have?
I just upgraded to libpng-1.2.15, and that didn't fix the problem. The old version was 1.2.14. (Of course, I ran revdep-rebuild after upgrading, which did nothing.)
I just upgraded to kwin-3.5.6, and this bug still occurs. The traceback looks the same, as far as I can tell.
The attached picture of a little blue ball doesn't crash anything for me in 3.5.7. (Haven't tested any earlier version, though.) Could you please try if this is fixed for you in 3.5.7?
I upgraded all of kde, but I get basically the same crash with kwin 3.5.7. Please let me know anything I can do to help track this down.
The attached picture also works well here with kde-3.5.7. Please include your emerge --info if it changed from your original report.
Neither reproducible with 3.5.6 nor 3.5.7 here.
In case anyone else runs into this, it seems the problem was caused by some sort of corruption in my KDE theme, which I'd customized. Changing it back to one of the defaults resolved the problem. (I thought I'd posted this information before, but it seems not.)
