See issue #611 and pull request #642. The warning previously added in PR #612 for Manuskript users with Qt 5.11 / 5.12 has shown itself, in my opinion, to be overly annoying. This is because the warning *always* displays on systems with the affected Qt versions even though the crash is verified to happen with the import feature only. Additionally the process to upgrade to a newer version of PyQt / Qt is not trivial for users who rely on pre-built packages and do not run from source code. Because the crash has been verified with the Import feature only, limit the scope of the warning to the Import feature.
