libsane 1.0.19-23ubuntu7 and  Epson Stylus RX500 (epson). 

I did also enable/disable the test backend in dll.conf, with the same result.

I'll try it again with 1.0.20 as the situation should be better there (as Olaf 
mentioned), but I guess I will work around it, by calling sane_exit/sane_init 
if sane_open hasn't been called yet.

What can be done to fix the underlying problem? Do you see it as a problem that 
will go away with time, or should I be prepared to keep the workaround 
indefinitely? Most frontends only scan for scanners at startup.

Thanks for the answers :)
