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.<br>My device is an Epson SX510W and i'm using the epson2 backend.<br>
<br>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.<br>
<br>If you need, i could reproduce this bug disabling backends one by one but not before this week end.<br><br>Best regards,<br><br>Enabled backends :<br><br>net<br>abaton<br>agfafocus<br>apple<br>avision<br>artec<br>artec_eplus48u<br>
