Hi, If you are using session bus then in the session bus conf file usually in /etc/dbus-1/session.conf it has message size limit. I think by default it is 1MB. So if that is the problem then may be you can try by increasing the message sixe limit. -Br Naveen <div class="gmail_quote">On Jan 21, 2008 5:53 PM, Thiago Macieira <<a href="mailto:thiago@kde.org">thiago@kde.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="Ih2E3d">Sumit Kumar Jain wrote: >Hi All, >I am using dbus glib binding.
