System Information
Win10 / GTX 1070

Blender Version
Broken: 2.78

Short description of error
I'm not sure we can consider it as a bug, but the layout alignment doesn't seems to be correct in all situations.
A simple example with row and column can show what seems wrong.

layout = self.layout
col = layout.column(align=True)
row = col.row(align=True)
row.prop(scene, 'prop_a')
row.operator('my_operator.btn')
col.prop(scene, 'prop_b')

Exact steps for others to reproduce the error
Run the script in the attached .blend file and check the result in the sequencer panel.

[UILayout.row ]] is not enough in this case. You have to use [ https:*docs.blender.org/api/blender_python_api_2_77_0/bpy.types.UILayout.html#bpy.types.UILayout.split | UILayout.split :

        scene = context.scene
        layout = self.layout
        col = layout.column(align=True)
        row = col.split(0.3, align=True)
        row.label("Prop A")
        row = row.row(align=True)
        row.prop(scene, 'prop_a', "")
        row.operator('my_operator.btn')
        
        row = col.split(0.3, align=True)
        row.label("Prop B")
        row = row.row(align=True)
        row.prop(scene, 'prop_b', "")
        row.operator('my_operator.btn', text='', icon='REC')
        
        row = col.split(0.3, align=True)
        row.label("Prop C")
        row = row.row(align=True)
        row.prop(scene, 'prop_c', "")
        
        row = col.split(0.3, align=True)
        row.label("Prop D")
        row = row.row(align=True)
        row.prop(scene, 'prop_d', "")

Or use 2 columns instead of 1:


        scene = context.scene
        layout = self.layout
        row = layout.row(align=True)
        
        col1 = row.column(align=True)
        col2 = row.column(align=True)
        
        col1.label("Prop A")
        row = col2.row(align=True)
        row.prop(scene, 'prop_a', "")
        row.operator('my_operator.btn')
        
        col1.label("Prop B")
        row = col2.row(align=True)
        row.prop(scene, 'prop_b', "")
        row.operator('my_operator.btn', text='', icon='REC')
        
        col1.label("Prop C")
        row = col2.row(align=True)
        row.prop(scene, 'prop_c', "")
        
        col1.label("Prop D")
        row = col2.row(align=True)
        row.prop(scene, 'prop_d', "")
