Note that it is not LyX crashing but rather Qt. Indeed, the crash occurs in the QtCore library. It was introduced in Qt 5.10 and is still present in Qt 5.11. Hence, the only way to solve this issue is either recompiling LyX using Qt 5.9 or waiting for a solution in the next Qt versions. The crash does not occur with LyX 2.2 only because Qt 5.9 is used there. -- Enrico
