Sylpheed bug?

[Torfinn Ingolfsen]

Hello!
Some things to check:
1) is Sylpheed the only program that makes your Xorg crash?
2) which DE (Desktop Environment) are you using? I'm using Xfce
3) are any "special effects" turned on in your Xorg / DE setup? Things
like Compositor, ...?
4) if "yes" in 3 - does it help if you turn off those "special effects"?
5) Are you using ports exclusively, or are you mixing ports and packages?

HTH
