switch to gscan2pdf, fare less crashes... I found when Simple Scan crashes, I will also lose my usb network card ( internal )... My gut feeling tells me there is and issue with Cups driver for All-in-One printers...

Subject: [Bug 843361] Re: simple-scan crashed with SIGSEGV in g_closure_invoke()
 
I am still affected by this bug as of this morning. I scanned three
documents in Simple Scan: the first had 2 pages, and the second/third
had 3 pages each. Simple Scan crashed while scanning the third page of
the third document. The scanner head ran to the end of the tray and
stayed there until I re-opened Simple Scan and told it to start the last
document over.

My scanner is an HP Deskjet F4180 All-in-One printer/scanner. The device
shows up in lsusb as:

Bus 002 Device 005: ID 03f0:7e04 Hewlett-Packard DeskJet F4100 Printer
series

Scan image quality is not affected; the scan in progress is simply
interrupted and lost.

I have so far been unable to reproduce the bug when running Simple Scan
via simple-scan --debug > simple-scan.log 2>&1, but I will keep trying.
I have installed xsane but have not tried using it yet; I plan to later
today and I'll report back with additional info when I can. This bug is
still very much real and interferes with my workflow every so often, and
I'd rather help it be resolved than see it expire. I previously had no
problems with scanning in 11.10, 11.04 and 10.04 with this scanner.
