Running with my LD_LIBRARY_PATH setup seems to avoid the problem. $ LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH git-cola
I was lead to attempting this by post at https://superuser.com/questions/1397366/what-is-wrong-with-my-qt- environment-it-reports-could-not-find-or-load-the-qt/1397518#1397518 It was noticed that in my debug of the Qt plugins and dynamic library use, multiple library paths were being selected: $ export QT_DEBUG_PLUGINS=1 $ git-cola QFactoryLoader::QFactoryLoader() checking directory path "/usr/bin/platforms" ...
