Ah! I missed that. But now it becomes familiar. Take a look at

	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=482126

there seems to be a change in Qt behavior (I'm running 4.4.0 here and
above bug did not happen with Qt 4.3). The bugreport also contains the
patch.

I'm pretty sure that this is not Debian-specific, so others will
probably be affected when Qt 4.4 is more wide-spread.


Running caret with:

	LC_ALL=C caret5

is a workaround for now (i.e. works for me).


Thanks,

Michael
