This is a twenty-five year old bug in the sample Xlib's implementation
of the X protocol XIM transport.  If an input method crashes, its
transfer window is destroyed by the X server, while Xlib thoughtlessly
continues waiting for events to be delivered from it...

We can do nothing about this problem except ask the I-Bus developers to
fix their crashes.  Meanwhile, you can disable XIM

  Emacs.useXIM: false
