Python: accessing DriverVariable targets causes segmentation violation
build 26658
Ubuntu 64 bit

Delete default cube
Add Armature > Meta-rig > Arm biped
In Armature context, Meta-Rig tab, check Create deform rig and Generate
Select the new rig
Run the following code.

-------------- Python file -----------

import bpy

ob = bpy.context.object
print(ob)
adata = ob.animation_data
print(adata)
drivers = adata.drivers
print(drivers)
for fcurve in drivers:
print(fcurve)
driver = fcurve.driver
print(driver)
vars = driver.variables
print(vars)
for var in vars:
print(var.name)
print(var.type)
print(var.targets)
for targ in var.targets:
print("Print target")
print(targ)

-------- Output ----------

[BPy_StructRNA "Object" -> "rig"]
[BPy_StructRNA "AnimData"]
[BPy_PropertyRNA "AnimData" -> "drivers"]
[BPy_StructRNA "FCurve"]
[BPy_StructRNA "Driver"]
[BPy_PropertyRNA "Driver" -> "variables"]
hinge
SINGLE_PROP
[BPy_PropertyRNA "DriverVariable" -> "targets"]

%%%Closed duplicate report:
[#21054] Python: accessing color ramp causes segmentation violation
https://projects.blender.org/tracker/index.php?func=detail&aid=21054&group_id=9&atid=498

Both of these bugs are caused when trying to iterate over collections that are defined as arrays in the sdna code.

Assigning our Python wrangler-master, Campbell :)
