Scanning, cutting multiple documents everytime crahes simple-scan

[Xwarman]

If I try to scan multiple documents (coloured) in a document, cancel the jobs to scan only half of site, rotate and cut, simple scan crashes reproducable every time after 3 or 4. scan.

console output after start:

(simple-scan:24270): Gtk-WARNING **: Unknown property: GtkDialog.has-separator

(simple-scan:24270): Gtk-WARNING **: Unknown property: GtkDialog.has-separator

** (simple-scan:24270): WARNING **: scanner.vala:1098: Unable to start device: Device busy
Speicherzugriffsfehler

I tryed it 4-5 times and everytime it is crashed.

Ubuntu 11.10 x64.

some drivers seem to have problems with receiving more commands while the scanner is busy.
this probably is a problem with the driver (backend), but it might be that simple scan is missing a "hey, scanner, stop scanning and do the following instead: ..." command.

However, you should read the linked article:

==============================================================
Hi there,

thank you for filing this bug and showing your interest in Simple Scan!

This seems to be a Hardware Issue, i.e. Simple Scan does not support your scanner perfectly -- or possibly not at all.

Unfortunately such problems happen more often then they should, and while it might indeed be a problem with Simple Scan, in our experience, most of the time it is not.
This is why we prepared a check-list at [1] that will let you find out whether or not it really is a problem with Simple Scan and what your options are in either case.

Please read that list and tell us how you decided to proceed. I will set this bug to "Incomplete", so a friendly robot will expire this bug in 60 days if you do not respond. However, we would really prefer to hear back from you!

Best Regards
Michael
