Package: libgtk2.0-0
Version: 2.24.20-1
Severity: normal
Tags: upstream patch
Dear Maintainer,
VNC is a commonly used graphical desktop "remote control" system:
http://en.wikipedia.org/wiki/Vnc
Copy and paste (using the standard X11 selection mechanism) from Iceweasel to
a VNC viewer session does not work ("clipboard" contents are not updated
within the VNC session).
Copy and paste of the same content from Iceweasel to an Xterm, and then, from
the Xterm to VNC does work. Only going directly from Iceweasel to VNC
fails...
I happen to use the vncviewer that comes with the ssvnc package, but I believe
this problem will occur with any VNC client.
This bug is long standing as I found this old report that describes the
problem and provides the gtk+ patch that fixes the bug:
https://bugzilla.redhat.com/show_bug.cgi?id=596748
In the above, the patch is described by Adam Tkac like so:
After more detailed inspection this is actually a bug in gtk2,
gtk_selection_owner_set_for_display() function doesn't handle
GDK_CURRENT_TIME macro well.
Essentially (as I understand it), most apps do not care about the time stamp
associated with a paste selection, but the VNC viewer is an exception as it's
looking to synchronize its concept of the "clipboard" across platforms so it
checks for "freshness".
Iceweasel time stamps its selection using GDK_CURRENT_TIME (I think this is
just a constant of value 0) and this is not considered to be "fresh" by VNC,
so it does not sync the clipboard...
The patch causes gtk+ to use the current time for GDK_CURRENT_TIME (not 0).
The patch is from Adam Tkac and looks like:
diff -up gtk+-2.21.1/gtk/gtkselection.c.firefox gtk+-2.21.1/gtk/gtkselection.c

The patch can be downloaded here:
https://bugzilla.redhat.com/attachment.cgi?id=422506
I've tested the patch on my own system like so:
cd ~/tmp
apt-get build-dep gtk+2.0
apt-get source gtk+2.0
wget -nd 'https://bugzilla.redhat.com/attachment.cgi?id=422506'
cd gtk+2.0-*
patch -p1 <'../attachment.cgi?id=422506'
debian/rules binary
dpkg -i ../libgtk2.0-0_2.20.1-2_i386.deb
The patch works perfectly for me and it resolves a bug that has bugged me for
a long time... :^)
Thank you for your time and consideration... It's much appreciated!

Iceweasel/Firefox doesn't use gtk2 any more so I'm closing this bug.
Thank you,
