chromium-browser does not work with nimf

[Hodong Kim]

chromium-browser does not work with nimf which is an input method framework.

You can download nimf at https://launchpad.net/~hodong/+archive/ubuntu/nimf
Run the following command in gnome-terminal.

sudo add-apt-repository ppa:hodong/nimf
sudo apt update
sudo apt install nimf
im-config -n nimf

Then, logout, login.

Run chromium-browser in gnome-terminal.
Then, you can see the following message.

[libprotobuf FATAL ../../third_party/protobuf/src/google/protobuf/stubs/common.cc:61] This program requires version 2.6.0 of the Protocol Buffer runtime library, but the installed version is 2.5.0. Please update your library. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "/build/mir-pkdHET/mir-0.21.0+16.04.20160330/obj-x86_64-linux-gnu/src/protobuf/mir_protobuf.pb.cc".)

chromium-browser in Ubuntu 16.04 is different from chromium in Debian Jessie.
chromium-browser in Ubuntu 16.04 includes libraries.

/usr/lib/chromium-browser/libs/libprotobuf_lite.so is different from
/usr/lib/x86_64-linux-gnu/libprotobuf-lite.so

This is the problem.

But, google-chrome and chromium in Debian Jessie work fine with nimf.
Try it.

Google Chrome
https://www.google.com/chrome/browser/desktop/index.html

Chromium in Debian Jessie

https://packages.debian.org/jessie/chromium
https://packages.debian.org/jessie/amd64/chromium/download
https://packages.debian.org/jessie/libjpeg62-turbo
