Please describe the problem:
When you define GtkAdjustment object in your interface file and "value" property tag is put before "upper", it gets reset to 0.
It could be just a glade3 bug but order sensitivity feels rather unintuitive in this case.

Steps to reproduce:
The easiest way is to write a small python script.

import gtk

ui = """
<interface>
    <object class="GtkAdjustment" id="adj-1">
        <property name="value">27</property>
        <property name="upper">100</property>
    </object>

    <object class="GtkAdjustment" id="adj-2">
        <property name="upper">100</property>
        <property name="value">27</property>
    </object>
</interface>"""

builder = gtk.Builder()
builder.add_from_string(ui)

for name in ("adj-1", "adj-2"):
    adj = builder.get_object(name)
    print "%s: upper=%.1f, value=%.1f" % (name, adj.upper, adj.value)


Actual results:
adj-1: upper=100.0, value=0.0
adj-2: upper=100.0, value=27.0


Expected results:
adj-1: upper=100.0, value=27.0
adj-2: upper=100.0, value=27.0

Does this happen every time?
yes
