If I run it from a console shell i get (once I close the application):
QMultiInputContext::changeInputMethod(): index=0, slave=xim
$ KCrash: Application 'soffice.bin' crashing...
XIO: fatal IO error 9 (Descrittore di file non valido) on X server ":0.0"
after 122 requests (122 known processed) with 0 events remaining.
This happens on both SL 3.5 x86_64 machines i use (a desktop PC and a protable PC).
Everithig works fine, only at exit there is this problem.
