Re: [Mplayerplug-in-devel] gtk2 problems with latest CVS

[Kevin D. <kde...@ya...>]

Alex,

This is interesting to me. I made the changes as you suggested and then fired 
up firebird 0.8 (gtk2-xft) and I got the error g_threads are already inited 
and then it died. So those recommendations are not going to go in.

I'm guessing that maybe you have browser that uses GTK1 widgets?
