kwrite (KDE4.1) show files empty

since the update to KDE 4.1,I have kwrite showing several files as empty (note there are no special characters inside those files).
If I open them with the kwrite/kde3 variant then the files are opened correctly (and look like how I remembered when opened with kwrite from kde 4.0).

Anyone else suffering from this problem, or even better aware of workarounds/fixes ?

bump : nobody else suffering from this ??

Yes I had it start with the last update,38 or so. Stll not fixed in 40.1
