There's a whole bunch of these in the Error Tracker so that'll be a useful data point when verifying the fix. Although, you'd need to dig into the Dependencies to find the sane-backends version.

[Test Case] 1. Run a SANE client on a system that is failing Avahi scans (exact cause not determined). Expected result: Client works without crashing. Observed result: Client crashes. [Regression Potential] Code fix could cause a change in behaviour of successful Avahi scans for Kodak devices, though the fix matches the Avahi documentation for correct usage.
