Hi. Today something weird : scanimage (scanimage (sane-backends) 1.0.21cvs;
backend version 1.0.21) is segfaulting. I putted a gdb trace in the tail.
My device is an Epson SX510W and i'm using the epson2 backend.
The only thing I know its this problem don't come from epson2 and network
package (I tested with only both of them in dll.conf and there is no problem
so i'm not affected. I think a lib update break it but which one is the
million dollar question.
If you need, i could reproduce this bug disabling backends one by one but
not before this week end.
Best regards,
