[sane-devel] scanimage/scanadf Segmentation fault

[Stefan Below]

Its an ltsp environment, and i have not installed scanimage&scanadf on 
the server side.Only saned is installed.  Maybe i can do the testing in 
a few hours.

I can scan with scanimage --mode Gray, but scanadf --mode Gray fgives me 
the seg fault.

But thats a little bit strange.I got the same error with scanimage, and 
now it works.

 I already did a fsck test, but everything looks ok.
