Can't copy out of pre-commit hook failed window

[liquidcms]

Sorry, not too familiar with git-gui or even working in Ubuntu desktop. Most things in the desktop seem to work as expected but I can't copy the text out of the pre-commit hook failed window that shows up when i use git-gui to commit.

Is this a git-gui bug or possibly an ubuntu issue (although I have not come across anything else in Ubuntu that was showing this issue)?
