Pidgin “Send screenshot” plugin

гm running Ubuntu 14.04 (x64) with Pidgin 2.10.9 (libpurple 2.10.9) and I cannot install "Send screenshot" plugin from .deb package on it'official сайт. If I try to, Программное обеспечение Center notifies я about bad package quality:

Lintian check results for /home/justlogin/Downloads/pidgin-sendscreenshot-0.8-3-amd64.deb:
Skipping /home/justlogin/Downloads/pidgin-sendscreenshot-0.8-3-amd64.deb: syntax error at line 18: Continuation line outside a paragraph (maybe line 17 should be " .").

Even when I choose "Проигнорировал and install option", installation fails.

How хан I add this plugin to Pidgin after all?
