      Since roughly 4.3.2019, Qt Creator crashes frequently when editing text near QComposeInputContext::ensureInitialized() . I have not managed to reproduce this with a simple example.

      It might be related to "platforminputcontexts: use libxkbcommon compose key API" 2065bc070dcd1f88a1f5ba3dd6ef0139a9a441ec https://codereview.qt-project.org/#/c/98062/ .

      Reverting the change seems to help at the cost of introducing warnings:

      qt.xkb.compose: error: xkb context has not been set on QComposeInputContext
