Created attachment 8476 screenshot If you open the properties of the plugin,the button - Close ,not translated into Russian. In the ru file.po all lines are translated and there is no line with the word Close at all.
I forced a translation synchronization, for some obscure reasons the file was not up to date. It will be available in next release. https://git.xfce.org/panel-plugins/xfce4-places-plugin/commit/?id=6dbe96a0cc3d4e7690c5bf9ff78486e2187fb8dc
