Ok, I've added the code necessary to do cleanup after widget destroy,
to make sure unneeded XIM's get freed.
However, as you can see below, doing the XCloseIM call crashes nedit,
not having the XCloseIM call doesn't crash nedit.
The first line in the new version of XmIm.c triggers the difference.
To reproduce :
- start nedit
- Control-O
- select a file by double-clicking
This'll crash in the destruction of the file selection box.
As the proof below says this is really a memory corruption,
we're not in XCloseIM any more.
Sigh. Any clues anyone ?
