I have a dual-head setup that only presents one "screen" to X (subdivided by xinerama).
If I run xwininfo -root -display :0.0 it works as expected, giving the root window information for my single "screen".
If I run xwininfo -root -display :0.1 it segfaults.
I expect it to exit gracefully with an error message. On Ubuntu 8.04 this error message used to be "cannot open display :0.1".
The problem could lie in libxcb (I'm no expert) xcb_connection_has_error() no longer returning true in the -display :0.1 case, but I've attached a patch for xwininfo anyway.
