I can't tell much from the backtrace, but could you tell me which
version of the PNG libraries you have installed? "rpm -qa |grep png"
should give the packages and versions. It's possible you have an update
to libpng that breaks our link to it. Now that I look at our Red Hat
build host, this seems quite likely (it's using an OLD libpng,
1.0.1-3). I'll try to get this fixed in future releases.
