Subject: texsync'd linux ConTeXt png error

I'm using the latest texsync'd version of ConTeXt on 32bit and 64bit
linux. Looks like either ConTeXt or pdfetex can't handle PNG's with an
alpha channel.
PNG image data, 8-bit/color RGB, non-interlaced <-- works fine
PNG image data, 8-bit/color RGBA, non-interlaced <-- corrupt pdf
PNG image data, 8-bit gray+alpha, non-interlaced <-- following error:
---
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
---
repeated ad nauseum
(To benefit anyone coming across this message in the archives:)
As a work around, assuming you don't need the alpha, the image can be
converted to RGB in The Gimp using Layers > Flatten Image.
Alternatively, using Image Magick, the command would be
convert image.png png24:image-new.png
