[sane-devel] scanimage OK, but problems with xsane

[Paul Bartholdi]

Hello,

I have a Canon Pixma MP970 connected via ethernet. On the other side, I use
a Sony Vaio with Ubuntu 8.10 and the latest csv sane.

scanimage -L , scanimage -T and scanimage pixma > Z.raw all work correctly.
No visible problem (SANE_DEBUG_PIXMA=10).

Now, when I try xsane, the scanner is found  etc, but I get the  following
problems:

- a red dot left of Preview on the Oreview window.
- when I pusj the <Preview> button, xsane hangs, no cancel works.
- when I push the <scan> button, the hardware moves correctly, lamps on etc.
but after the scan, xsane hangs again, every things frozen. Apparently no
data have been transmitted.

I guess I have a problem of connections between the various parts of xsane.

Here i a short sample of the DEBUG output:

(xsane:24892): Gtk-WARNING **: GtkSpinButton: setting an adjustment with
non-zero page size is deprecated

strace -f gives 25000 lines...  nothing easily interpreted from me. What
should I look for on the trace?

Any hint is welcomed!    Thanks,     Paul

PS Should I attach the strace file?
