Bug 97758 – WebKitGTK 1.10.0 cannot start due to communication error with X

• Status: RESOLVED
• Resolution: INVALID
• Component: WebKit2

[Christian]

I have upgraded to WebKitGTK 1.10.0, however, when I start it I
get the following:

Acquired a message bus connection
(II) pvr(0): gdlHideCursor
Xlib: sequence lost (0x10000 > 0xe2) in reply type 0x0!
Xlib: sequence lost (0x10000 > 0xe2) in reply type 0x0!
Xlib: sequence lost (0x10000 > 0xe2) in reply type 0x0!
Xlib: unexpected async reply (sequence 0x1)!
Xlib: sequence lost (0x10000 > 0xe2) in reply type 0x0!

Seems like some problem with the interaction with X. Have you seen this before?

I have tried to run the MiniBrowser from gdb and got the following
trace when quiting after the "Xlib: sequence lost (0x10000 > 0xe2) in
reply type 0x0!"

Furthermore, I have tried to downgrade webkit to webkit 1.8 again. This gives
the same error, so I'm thinking it might be a problem with some of the
dependecies that I have upgraded during the webkit upgrade. My upgrades include:

GLib -> 2.34.0
GTK+ -> 3.4.4
Pango -> 1.30.1
GDK -> 2.26.4
libsoup -> 2.40.0
GTK+-2.0 -> 2.24.12
Atk -> 2.6.0

After upgrading a couple of libraries I know get the following:

at-spi2-core -> 2.6.0
at-spi2-atk -> 2.6.0

This bug was related to updating GTK+. The newer version of this only supports Xinput-2 however this was not supported in my setup, therefore each time an Xi2 event occured the application would crash.
