Recently, Chromium stoped to open downloaded files. If i download and open doc file from chromium, in command line i see the following message: /usr/lib/libreoffice/program/soffice.bin: relocation error: /usr/lib/x86_64-linux-gnu/libgdk-3.so.0: symbol mir_display_config_release, version MIR_CLIENT_0.21 not defined in file libmirclient.so.9 with link time reference If i download pdf file i see the same message with evince instead of libreoffice. It looks like more general problem, but I still can open files from these two applications or using xdg-open. I tried to work with new chromium profile, but i get the same message no matter what and files cannot be opened.
