Confirmed.
Comment 2 Michal Jaegermann 2004-12-07 18:09:09 EST 
Everything nicely starts and scans if one will rename an existing
~/.sane.  I did not try which of files in this directory is really
a culprit (they were two in ~/.sane/xsane and now I have three).
The reaction is indeed somewhat extreme. :-) 'strace' ends up with

--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

This detail that it started to ask me again about accepting
a license was a giveaway.
Comment 3 Daniel Malmgren 2004-12-08 04:26:47 EST 
Confirming Michals workaround. Removing ~/.sane/xsane/xsane.rc made
xsane work again (though of course all my settings were gone).
Comment 4 Tim Waugh 2004-12-08 04:33:25 EST 
It will ask about the license *anyway* when you upgrade versions.  I think this
is due to some settings moving into a different file.  I need to talk to Oliver
Rauch about it.
Comment 6 Tim Waugh 2004-12-08 07:16:21 EST 
Fixed in 0.95-2.
