synaptic Gtk-CRITICAL gtktreeview.c: line 4881 (gtk_tree_view_bin_expose): assertion `has_next' failed

Binary package hint: synaptic

Performing certain operations in synaptic causes the following message:

(synaptic:8990): Gtk-CRITICAL **: file /build/buildd/gtk+2.0-2.14.4/gtk/gtktreeview.c: line 4881 (gtk_tree_view_bin_expose): assertion `has_next' failed.
There is a disparity between the internal view of the GtkTreeView,
and the GtkTreeModel. This generally means that the model has changed
without letting the view know. Any display from now on is likely to
be incorrect.

I can reproduce this by:
1. Open synaptic
2. Search for "kdebase"
3. Mark for installation "kdebase-dbg" (and it's dependencies)
4. Switch to "Custom Filters->Marked Changes"
5. Unmark "kdepimlibs-dbg" and its dependencies (kdelibs5-dbg and libqt4-dbg)

That's how I found it, but I think it's pretty generic. It also happens if I install "3dchess", without searching, automatically selecting it's dependency "xaw3dg", then go into "marked changes" and unmark xaw3dg (and hence 3dchess).

Kubuntu 8.10, fully updated
synaptic 0.62.1ubuntu10
libgtk2.0-0 2.14.4-0ubuntu1

Thanks for your report.

I can't reproduce it with the latest release. Is it still an issue for you ?

[Alan Jenkins (aj504)]

I can still reproduce it using the 3dchess example. Note that the message is on stdout/stderr - you have to run synaptic from a terminal in order to see it.

[Jean-Baptiste Lallement (jibel)]

Confirmed with the 3dchess example in lucid.

Thanks.

Still happening on Quantal.
