Xlib: unexpected async reply

["Fernando Apesteguía" <fernando apesteguia gmail com>]

Hi list!

I get this error when runing my GTK application:

Xlib: unexpected async reply (sequence 0xdfd)!
(Te sequence number varies.)


A little explanation about the application:

It runs two threads. One of them is runing inside the gtk_main() loop.
The other one, periodically reads from different files and updates the
labels in the window. I use gdk_threads_enter() and gdk_threads_leave() to
block the other thread.

The aplication has a Tabbed Pane. Each tab shows information from a
different file.

Now, I get this error when I try to see the information showed by the last
tab I added. Basically, the cycle I implement is (pseudocode):

infinite_loop{
  ...
  if tab1_is_visible{
    update_tab
  }
  ...
 pause;
}

and update_tab performs:

read_value_from_file();

gdk_threads_enter();
  update_labels();
gdk_threads_leave();

Since the error is realted to Xlib, I think I'm doing something wrong about
multi-threading, but I can't find what.
I'm doing as I did with the other tabs and I hadn't any errors like this

I've read http://mail.gnome.org/archives/gtk-list/1999-July/msg00438.htmlbut
I think this does not match my problem. I'm not calling to gtk
functions
from callbacks or signal handlers.

Any suggestions?

Best regards!
