[Q] Failed to move application, There is not enough storage left

Scenario:

/data: 279/310mb
/data/sdext2 172/483mb
/system 117/123mb

Link2sd installed.


When I install a 1mb-size app, it goes to SD card (not linked to ext partition on sd. Just moved to fat32 by app2sd). So I try to move it back to phone OR link it to ext partition with Link2D but I get the error:

pkg: /mnt/asec.... .apk Failure [Intall_Failed_insufficient_storage]


Whey I try to move the app with built-in Application manager I get:
Failed to move application, There is not enough storage left


What's wrong with that?
