Bug 575130 – gtk apps segfault with x2go

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Inbae Jeong 2016-02-19 12:28:48 UTC]

Gtk apps started to segfault with x2go after updating world.

Someone suggested cairo[xlib-xcb], but it didn't help with nor without the flag.

All gtk apps segfault so I suspect some gtk-related things got broken but I'm not sure.

I append the backtrace and emerge --info.

I got a fresh install and this is not happening anymore. I don't know what the problem was, but it works now.
