libpng error: Call to NULL read function

Comment 1 Wim Taymans 2006-03-24 20:26:56 UTC

might be fixed by recent commit to make the state change function thread safe..
see:

http://freedesktop.org/cgi-bin/viewcvs.cgi/gstreamer/gst-plugins-good/ext/libpng/gstpngdec.c.diff?r1=1.20&r2=1.21

It certainly looks from the backtrace that the datastructures were cleared while the streaming thread was still running (generating the message).

Closing, reopen if needed.

Problematic image

I opened this bug in Launchpad too. When Rhythmbox try to scan this image, it crashes. Also with: "gst-launch-0.10 -t filesrc location=/media/sdb1/backups/images/buttons/usa-firefox.png ! decodebin ! fakesink"
