Without seeing more of your code, I'd have to guess that the IM is using the XID of window2 as its "parent" and when you close window2, without closing the IM, then it tries to utilise the now-invalid window handle and segfaults. If that is the case, then you will need to (somehow) ascertain if window2 has an IM open on it when it closes, and if it does explicitly close the IM before you allow window2 to be removed. An alternate approach might be to set the IM to use the handle of a window that will not disappear, but then the problem is how to direct the input from the IM to the correct window...
