Phoca Gallery Plugin make totally crash on the backend

[Zotius]

I want to use Phoca Gallery Button plugin on the backend.
My Joomla version is the newest 2.5.3
I've installed all of the required things: Phoca Gallery Component, Phoca Gallery Plugin, Phoca Gallery Button Plugin:

• • com_phocagallery_v3.1.5.zip
  • plg_editors-xtd_phocagallery_v2.7.1.zip
  • plg_content_phocagallery_3.1.2.zip

The plugins - naturally - are enabled.
On the backend when i want to start editing an article I see this:
The administrator screen totally crashed:

The Error message is:
"Fatal error: Call to a member function getTemplate() on a non-object in /home/zotiushu/public_html/plugins/editors-xtd/phocagallery/phocagallery.php on line 24"
What is the solution?

I managed to solve the problem with the newest version of the Phoca Gallery Button Plugin.
(plg_editors-xtd_phocagallery_v3.0.0.zip to J1.6)
