Re: Re: [kde-sunset] kmail-3.5.10 crashes

I don't think I had any traces of libpng1.2. I followed these steps for updating my libpng.

http://blog.flameeyes.eu/2010/06/29/stable-users-libpng-update

So I had no traces of the old version. I haven't been using --as-needed.

I depclean and revdep after every update, I have buildpackage in my features. My machine is already doing it's revdep back to 1.2. Hopefully it will be done when I get back in to work tomorrow. I'll let you know if that helps.
