Hi!

I am running Debian unstable. Some Weeks ago i upgraded my Kernel to
Linux-2.6.6.
Yesterday i noticed, that Xsane crashed with a segfault. However, i am
still able to scan with Xscanimage and scanimage, so this might be a
Xsane Bug.

When using Kernel 2.4, i used the module scanner, for accessing my usb
scanner.
 (Actec e+48 u). Everything worked fine.

The scanner module is now removed from the kernel,as announced. 
Now if have to use libusb to access my scanner. However, this does now
work anymore with Xsane.

Anybody has the same problem? Are there some workarounds?

I did a
strace xsane
This are the last words of xsane until the segfault:
