Comment 6 for bug 1446746

Thanks for the quick response. Those library packages are not installed here:

chaas@aldi:~$ LANG=C sudo apt-get remove libgit2-lib libgit2-glib
Reading package lists... Done
Building dependency tree

E: Unable to locate package libgit2-lib
E: Unable to locate package libgit2-glib

Version 3.15.1-0ubuntu2 of gitg is installed. There are no pending updates.

The error message I get is similar to the OP's:

** (gitg:28040): WARNING **: gitg-plugins-engine.vala:40: Could not load repository: Typelib file for namespace 'Peas', version '1.0' not found

I also purged gitg and ran "apt-get autoremove" and reinstalled gitg. Same effect.
