Qt Creator 4.11.0, from Manjaro Testing branch.
I downloaded libGitQlientPlugin_1.0.0-qtc4.11.x.so.
When I open Qt Creator, open a project, and switch to Git panel, I get the following terminal error, then Qt Creator exits:
"/home/nyanpasu64/Dropbox/encrypted/code/exotracker"
qtcreator: symbol lookup error: /home/nyanpasu64/.local/share/data/QtProject/qtcreator/plugins/4.11.0/libGitQlientPlugin_1.0.0-qtc4.11.x.so: undefined symbol: _ZdlPvm, version Qt_5
ConnectionServer error: "QLocalSocket: Remote closed" "/tmp/QtCreator-CLqyde/ClangBackEnd-18652"
The first time, Qt Creator froze (possibly due to mechanical disk iowait). I launched Qt Creator from .desktop file and could not see what was printed to the terminal.
