[MENTION=4746176]michelsberg[/MENTION], [MENTION=4656455]zige[/MENTION], [MENTION=4458991]eddy4823[/MENTION] : Since I'm not really sure where the confusion lies, let me summarize the 2 areas where a "wipe" is needed.

Switching to PA GApps from another GApps provider: In this case, all that is needed is a wipe of the system partition as outlined in FAQ #8. Using this method you won't lose any of your data or application settings if the steps included are followed. This is necessary because different GApps providers use different name for the Google apps and a mixture of both would have catastrophic consequences.

Installing Google Camera, Keyboard, or Calendar - FOR THE FIRST TIME using PA GApps. In this case, a CLEAN install is required as outlined in FAQ #3. Of course, a Clean install means you WILL lose all your data and application settings, however this is a one time only step. After this initial install, you can freely update these apps from the play store or any future PA GApps package.

- The reason this requirement was added was that 6-8 months ago almost every other posts in the KitKat GApps thread was from users complaining about FC's in Google Camera and/or Google Keyboard. However, EVERY time the user reinstalled with a Clean flash, the problems went away. As a result, it was decided to add this requirement to the Google Stock package and, ALMOST IMMEDIATELY, the problem reports vanished. I can't remember the last time we had one of those complaints in here, so I know it was a good decision. Does this mean that if you don't follow those procedures that you're going to have problems? Absolutely not. I've done it myself with no issues. However, requiring a Clean flash almost guarantees that there will be no problems - and I like that idea very much.

EDIT: In hindsight, adding Google Calendar to this list may have been an overreaction. I may remove the requirement for Google Calendar in a future update.

Adding "+Gallery" only prevents the GApps installer from REMOVING the Gallery that comes with your ROM. If you look at System_Files_Before.txt in your log files, you'll see that Gallery is nowhere to be found on your device BEFORE the GApps install even started. You might check with your ROM dev and see if they include Gallery. If they do, you will need to re-flash your ROM, along with these GApps, and everything should be fine.

I just checked your logs and they do show the "/system/vendor/lib/mediadrm" folder that I mentioned earlier. So I can't really say what the issue might be except that it really hasn't been reported by many, so I would assume you're right and that it's ROM related.

First of all, I wouldn't worry too much about it. You're not going to experience any problems as a result of the duplicate files. However, I did check and your ROM dev is definitely including the Google proprietary files below in his/her ROM. Since I've never seen any other ROM dev include this files (they are clearly from Google and would never be in any AOSP source), I can only conclude that this was an oversight.

Read FAQ #4 for what to include. As to your issue, it is very strange, indeed, but the logs will answer all the questions for sure!
