Workaround patch

Build Information:
SVN 25787
--
Reproduction:
==============
- WS > Edit > Preferences > Protocols > DLT_USER > Edit
- Add a couple of entries. 
- Select one entry.

Problem:
==============
One would expect the Delete and Edit buttons (and either or both of the Up and
Down buttons) to become active. However, it doesn't happen.

Workaround:
==============
The attached patch fixes the problem (at least on my Windows XP machine), but I
can't be sure if this is only a workaround and not the solution.

Investigation:
==============
Debugging with VS2005EE shows that this line:
        rep->selection =
gtk_tree_view_get_selection(GTK_TREE_VIEW(rep->clist));
results in rep->selection remaining null and therefore the subsequent
g_signal_connect on it has no effect.
