Thanks for localizing that. I was aware that sometimes a cancel call would 
trigger a segfault, but haven't had tiem to investigate further. BTW, is it 
possible that something in sane itself has changed regarding this during 
the last few versions? I got a couple of reports on this in the last 
months, before that it seemed never to be an issue.

OK - maybe it was backend-dependent as well.

I'm not sure why I try to open the empty device. On first start, it should 
ask for a list of devices and on next calls, use the last selected one. 
I'll check.

In the ini file the currently selected device has an entry somewhere. The 
name should be an exact match of what the backend returns as device name.

My list of critical bugs is getting too long for my liking (a handful, but 
still) so I probably will take some time next week to fix the bugs and 
release a new version. Users having problems should'nt hesitate to bug me 
if that takes too long :-)
