calligraflow should be able to produce flowchart with either "Basic Flowchart" or "Flowchart" from the "Stencil Box". However, the flowchart is missing.

Reproducible: Always

Steps to Reproduce:
1. With a clean installation of calligra-flow (meaning there is no calligra-flow installed before).
2. Run it, there is no "Basic Flowchart" at the "Stencil Box".
Actual Results:  
No "Basic Flowchart" in "Stencil Box".

Expected Results:  
"Basic Flowchart" should appear in "Stencil Box".

This problem appeared in version 2.5.3 as installed in Arch Linux. Besides that, the problem also existed in git (http://quickgit.kde.org/index.php?p=calligra.git&a=blob_plain&h=301342fddb4e896f35651f043e87f33ff8acb834&f=flow%2Fstencils%2FBasic_Flowchart%2Fcollection.desktop)
In order to make the "Basic Flowchart" to appear, need to add
X-KDE-DirType=odg-collection
to the "collection.desktop".
However, this only solves the problem of the appearance. Adding the shapes in the "Basic Flowchart" is still failed.
This problem does not existed in version 2.4.0 as installed in Linux Mint, where the "Basic Flowchart" is called "Flowchart". If the Flowchart is copied to the user directory, it can works with 2.5.3.
