Xlib: unexpected async reply (sequence ......)

["MERT TUGCU" <merttugcu hotmail com>]

Dear all,

I have been trying to solve this problem for a long time with no success. I 
have a video application which shows the video stream, captures an image and 
make some processing on the captured image. Therefore, I have divided the 
screen into 4 and show video, images and so on in each part of the screen. I 
search the internet and this problem shows up if your application is 
multi-threaded. Since my application has to be multi-threaded (because of 
the video stream), I am frequently getting this error and the application 
crashes.
Now, as far as I've seen, there are two things that could be done. One, is 
using the gdk_threads_enter / leave() pair. Do I need to use this pair 
whenever I need to update the GUI? Also I saw in one web page that I also 
need to use XInitThreads() function and this might solve the problem which 
did not.
Can someone please give a solution to get rid of this problem? I also looked 
to the GTK+ FAQ. I've seen that a lot of people are struggling with this 
problem.
Thank you for your time.
