Re: Meld for OSX / GTK issues

[Kai <kai willadsen gmail com>]

Hi,

I'll address the technical details in another email when I can, but I
just wanted to say how sorry I am for your brother and his family. I
can't begin to appreciate what this was like for you. Please know that
your contributions here are valued, but also that no one should
hesitate to take whatever time they need to away from open source.
Also, thank you for sharing your brother's story.

thanks,
Kai
