Comment 3 for bug 9743

apt-get install tla is working fine.
Synaptic crashes for any package that has dependencies. tla was used as an example.
I may be wrong, but I guess the cause of the problem is upgrading
libgtk2.0-0(2.4.10-1ubuntu1 => 2.5.4-0ubuntu1) which happened during Warty to
Hoary upgrade.

I'm getting the following output in a gdb session:
(synaptic:4515): Gtk-CRITICAL **: gtk_tree_view_unref_tree_helper: assertion
`node != NULL' failed

Program exited normally.
