NoneType error in dataflow.py->clear_path

[GoogleCodeExporter]

What steps will reproduce the problem?
1. decompile e.g. the app "com.mobisystems.office" (OfficeSuite Viewer 6)

    c = androguard.decompiler.dad.decompile.DvClass(classItem, dx)
    c.process()

What is the expected output? What do you see instead?

Expected: Successful termination of c.process(), access to decompiled class 
source
Actual: NoneType error:

ERROR    analyser.call_function  - 'NoneType' object has no attribute 'ins_range'

What version of the product are you using? On what operating system?
1.9 (rev. a1236a4a83e6)

Please provide any additional information below.
In dataflow.py:186, graph.get_node_from_loc(loc1) returns None (for loc1=38).
