Plugin crashes with Xulrunner 1.9.2/libpng/libjpeg

[Andreas Radke]

I'm building for ArchLinux the packages. We are currently updating libpng and libjpeg
at once and need to rebuild/fix openjdk.
When I understand it right with new xulrunner 1.9.2 it's no more possible to build the old
plugin (configure passed but the build quickly fails).

With npplugin I get this: 
checking for XULRUNNER... configure: error: Package requirements (      nspr mozilla-js mozilla-plugin libxul-unstable >= 1.9) were not met:

No package 'libxul-unstable' found

I have to apply sed -i "s/libxul-unstable/libxul/" configure.ac to pass configure.
The pkg builds fine then but as soon as the plugin is called the browsers gives a segfault.

Checking with ldd /usr/lib/mozilla/plugins/IcedTeaNPPlugin.so gives:
	libxul.so => not found
	libxpcom.so => not found
How does that come?



Something else: I have to apply this for the new libpng 1.4.0:

         goto done;

     success = SplashDecodePng(splash, my_png_read_stream, stream);

I hope this is the proper change to replace the deprecated function and not causing the trouble.
The function is also called here but I don't know how f it is has to be changed there:
[andyrtr at workstation64 trunk]$  grep -r png_check_sig src/*
src/icedtea6/openjdk/jdk/src/share/native/sun/awt/libpng/png.h: * png_check_sig(sig, n) := !png_sig_cmp(sig, 0, n).

src/icedtea6/openjdk/jdk/src/share/native/sun/awt/libpng/CHANGES:  Changed libpng.txt to demonstrate png_sig_cmp() instead of 

and we will have to find fixes for libjpeg ver 8. Is there already something floating around?
