trying to get rid of a persistent log warning debugging on Huawei Ascend P6

Question

I used to test my app on SGS 2 I9100 (4.1.2), after the device became defect I purchased a Huawei Ascend P6 (4.2). I have to always connect it in HiSuite mode which launches their annoying sync software on PC, USB debugging won't work otherwise. Ok, I got used to it but anytime I run my app I see this log (marked as WARN) and tagged with my app (the app still runs without any issues):

The problem is that this warning in the ONLY thing I see in LogCat, it somehow blocks all other messages even if a real exception occurs. To be exact: yes, I see only the message posted above and nothing else every time I run the app. As far as I understood, the system tries to get some resource which isn't even part of my project. But I have no clue why any other LogCat output does not appear. Anyone any idea what that is and how to fix it?

Does it occur repeatedly while your app is running? That'd explain why you can't see your own logs. Also, did you try putting a file at the path shown in the stacktrace? — TomTasche
it appears immediately after I start my app. Then it seems the session filter I have set up for my app just dies. Example - timestamp 11:20, this warning appears. Then no matter what and for how long I do with my app, no other messages will appear. That message at 11:20 will stay the only one. Yes, I also tried to create /data/cust/xml/hw_launcher_load_icon.xml in my project, putting some random drawable there - with no effect at all — Droidman
Did you also create a file at this path on your phone's file system? (you might need root for that) — TomTasche
where exactly on the file system? It seems I can only access directories contained in the directory which getExternalStorageDirectory() returns. That is /storage/emulated/0 There's also an /Android/data folder but I doubt it's the correct one — Droidman

As a person developing on a Huawei Ascend P6, this error only happens for me if I include a theme that is a theme inside the android namespace when defining an Activity (or the entire Application), leaving me to think that theme support is broken on Huawei's Android 4.2.2.
