Hello, current HEAD (2f61120c10da9128357510debc8e66880cd2bfdc) segfaults when I'm trying to do the following:
I add this to qemu's command-line: -chardev spiceport,id=charserial0,name=org.qemu.console.serial.0 \ -device isa-serial,chardev=charserial0,id=serial0 and then use spicy to connect to that machine. That spits out the following error: GSpice-Message: main channel: opened port 0x7f74182366e0 org.qemu.console.serial.0: opened (spicy:32386): GSpice-WARNING **: incomplete link header (-104/16) (spicy:32386): GSpice-WARNING **: incomplete link header (-104/16) GSpice-Message: main channel: closed I can see that the console works when the window flashes, so there was some communication done (Im running the kernel inside with "console=tty0 console=ttyS0,115200n8" as suggested here: http://lists.freedesktop.org/archives/spice-devel/2014-January/015919.html The full command-line with backtrace of all the threads (with abort()-ing thread being thread #1 follows. Let me know if I can help anyhow.
