simple-scan crashed with SIGSEGV in hpaioPmlDeallocateObjects()

I'm quite sure that it's a duplicate of bug 902830.

I can for sure reproduce it with the following steps:

 - Click Scan button and wait for ~5s while the scanner is initialized
 - Unplug and plug back the cable
 - A "Failed to scan" message appears
 - Ignore it, click the Scan button again
 - ... it crashes!
