Scripting: Converting Text object to Mesh object fails due to incorrect context (2.78) I'm new to scripting in Blender, but after extensive googling and searching through the API, I've created the following script to create an empty scene (my default scene has no cube, light or camera in it), add a Text object, set some various parameters, and then convert it to a mesh. However, when trying to convert to a mesh, I get:

RuntimeError: Operator bpy.ops.object.convert.poll() failed, context is incorrect


The following is my script:

import bpy

font_loc = #set to font location

bpy.ops.wm.read_homefile()                       #load default (empty) scene
bpy.ops.object.text_add()                        #create the text object
mytext = bpy.data.objects["Text"]                
mytext.data.body = "A"                           #set some stuff up
mytext.data.align_x = "CENTER"
mytext.data.align_y = "BOTTOM"
mytext.data.extrude = 0.1
fnt = bpy.data.fonts.load(font_loc)              #font loading works
mytext.data.font = fnt
bpy.context.scene.objects.active = mytext        #make sure my Text object is correctly selected
mytext.select = True
bpy.ops.object.convert(target="MESH")            #&lt;------ context is incorrect?


On that last line is when I get the error, but if I type that exact same line into the in-editor console after the script exits, it converts the Text object to a Mesh object perfectly fine. What's going on? Is there some other way to convert the Text object that I can't find?
bpy.ops.wm.read_homefile() - kills your current file and causes the trouble. If you could avoid it, it will work. I think you can import a scene from some blend file instead.
