[cairo] DirectFB backend supporting (crashed (Segmentation fault))

Sat May 11 06:41:54 PDT 2013

Hi,

My application crash with gtk-directfb, some extra information is following:

I follow the track and found it crash when calling "gtk_dialog_run()" in function connect_dialog(SpiceSession *session),

du to google's info about for "http://www.gtkforums.com/viewtopic.php?t=1330", i have tested that if i create dialog with "gtk_dialog_new()", it works fine…

someone have ideas with this ?

gtk+ version: 2.24.15
directfb version: 1.6.1
cairo version: 1.12.14
