Don't know to reproduce, but randomly the xdg popup will crash the compositor

Would be nice if you could compile with debugging symbols or even ASAN and then attach a stacktrace.

In any case, in #2172 I'm rewriting the whole IM thing so I'll look at this bug after finishing with the said PR.

It's so random; it may take hours. If that happens more frequently and I find a way to reproduce the issue, I will enable the debug symbols as you suggested.
