Package: libsane1
Version: 1.0.31-4
When I scan a document with simple-scan, which uses libsane1 in Debian
Bullseye the application crashes with a segmentation fault when I slick
the "scan" button.
I am using a HP, Inc ScanJet 4200c ( 03f0:0105 ) scanner.
I started simple-scan in gdb and got this backtrace:

I applied this patch to libsane1 and then the bug was gone and scanning
was working again:
