I'm trying to debug window.c. But I have no idea if that's what =E2=80=98json-read-string=E2=80=99 tries to read. > A bisect would be great too, of course. Is this a recent problem? I've seen it yesterday for the first time. I can't reproduce it reliably but it can hit any time, often when next stepping with gdb. Also I wasn't able to reproduce it on Debian so far. Bisecting on Windows is a pain here. martin
