Thank you for the report. Would you mind giving some examples of Russian letters so that I can try to reproduce the issue? No idea. Beside, need to reboot every time to reproduce it, as it stop crashing after nautilus started once. But after full reboot it crash 100%.
I did not want to share all my homedir file names, still i hope copy of terminal output will be useful
