I'm not sure about the relation. It would be better to have screenshots to compare.
Assuming that the bug could be related to language, I uninstalled Brazilian Portuguese, left everything in English and restarted Ubuntu.
The procedure for test is double click files DOC, DOCX and ODT in Nautilus. After 6 or 7 open files, the error still happens and the menus and tool bars are like that.
