Crashed when scanning second side in ADF of HP ScanJet 8270

[David King]

I maintain the Simple Scan package in Fedora and a user has filed a bug report about a crash. From the downstream bug report:

Simple Scan crashed while scanning a two-sided document using a HP Scanjet 8270's automatic document feed. It scanned the front side correctly, but crashed while scanning the back side.

The crach is reproducible and it always happens when scanning the back side of a document from the ADF. XSane does not crash, but fails to safe / recognize the back side and only safes the front of the page (when scanning to multi-page project).

Version-Release number of selected component:
simple-scan-3.10.3-1.fc20

Here's the output of

`simple-scan --debug > simple-scan.log 2>&1`

when the crash occurs and when simple-scan ends with `Segmentation fault (core dumped)`

Thanks !
