I added this because it seams impossible to understand if
the process has been interrupted using KScanDialog.

BTW There's a related bug in it, I remember I've already
discussed in this mailing list in the past, if my scanner
HP PSC 1610 -scanner and printer- is OFF, the plugin
crashes. 
That seems to be related to kscan but my knowledge here
is almost null. 
I tried to unroll KScanDialog::getScanDialog
and but even if i saw it worked as well my
test on some pointers didn't give more feedback
to the problem.
I believe the problem comes from udev and the
device that is not on system until the scanner
is switched on. 

Now there are two problems:
1) avoid plugin to crash
2) open a bug report but tho whom? kooka/libkscan?

Thanks,
	Angelo
