Description of problem:
matej@mitmanek: ~$ rpm -q gedit
gedit-3.14.3-1.el7.x86_64
matej@mitmanek: ~$ rpm -ql gedit|grep lib64/.*/plugins
/usr/lib64/gedit/plugins
/usr/lib64/gedit/plugins/docinfo.plugin
/usr/lib64/gedit/plugins/filebrowser.plugin
/usr/lib64/gedit/plugins/libdocinfo.so
/usr/lib64/gedit/plugins/libfilebrowser.so
/usr/lib64/gedit/plugins/libmodelines.so
/usr/lib64/gedit/plugins/libsort.so

matej@mitmanek: ~$ rpm -ql gedit|grep lib64/.*/plugins|wc -l
13
matej@mitmanek: ~$ 

But when I build the package locally (I guess the point is that gedit-3.14.3-1 was build when libpeas was still not present or something?) I get

matej@mitmanek: gedit (rhel-7.2 %)$ rpm -qlp x86_64/gedit-3.14.3-1.el7.x86_64.rpm |grep lib64/.*/plugins|wc -l
123
matej@mitmanek: gedit (rhel-7.2 %)$ 

(missing plugins include External Tools, Snippets, QuickOpen, which are quite useful).

Unfortunately python plugins need some more patching:
