[java-gnome-hackers] Xlib: unexpected async reply

[Stefan P. <st...@pr...>]

Hi all,

I have a fairly complex java-gnome application which produces the
following exception after some time:
  Xlib: unexpected async reply (sequence 0x316e)!

Before this happens I use several signal handlers (MenuItem.ACTIVATE,
TreeView.ROW_ACTIVATE, Button.CLICKED) to open dialogs, modify data and
close them again. The error usually occurs after the last dialog is
closed and only the main application window is visible.

I failed writing a stripped down application that produces the same kind
of error.

Searching around I found a posting [1] which explains that manipulating
widgets from another thread might cause this problem, unless proper care
is taken (which I don't if java-gnome does yet).  

I did not add Java threads to my application, so all I did was relying
on the threads provided by the underlying GTK+/java-gnome library.

Has anyone of you experienced something similiar before and can advise
me what might cause this issue?

Cheers,
  Stefan
