I'm puzzled. Where do you get "these"? Is this a message logged in the
QTextEdit - if so this is not related to Qt but to the logged process.
Otherwise xcb_io.c is not part of Qt. This is probably a problem with your
system, see for example:
http://www.redhat.com/archives/rhl-list/2007-November/msg02674.html
Which Linux distribution is this? Have you tried updating it?
