expected behaviour without gtkbuilder

Back in 2012 I wrote an app that used GtkBuilder extensively, and it featured a GtkEntry and associated GtkEntryCompletion, which all worked well at the time.

Unfortunately I can't pin down the exact moment this bug was introduced, but I've recently discovered that the GtkEntryCompletion does not function correctly on either Ubuntu Raring or Ubuntu Saucy. 

The expected behaviour is that the GtkEntryCompletion drops down a list of possible completions for the text entered in the GtEntry, but the observed behavior is that GtkEntryCompletion pops up a 1px tall box that is only visible due to it's drop shadow, and does not display any useful information. 

The GtkListStore in use is correctly populated by my code (so I've ruled out the possibility that the GtkEntryCompletion is correctly displaying an empty model), and the GtkEntryCompletion functions as expected when it is constructed in code. The bug is only present when GtkEntryCompletion has been constructed with GtkBuilder.

Attached are two example scripts, one demonstrating the expected behavior (without using GtkBuilder), and one reproducing the bug with GtkBuilder. Note that there is no (usable) completion drop down with the gtkbuilder version.

GtkEntryCompletion: call setter for "text-column"

Call gtk_entry_completion_set_text_column() when setting the
"text-column" property directly.

The completion appeared empty when setting "text-column" directly (for
example from a GtkBuilder file), because the setter creates and adds the
GtkCellRendererText.
