Hi,<br>
<p>
I installed xscanimage as a plug-in for GIMP. The dummy devices<br>
pmm:n work, so I guess, the basic installation is ok.<br>
<p>
When I select my scanner (umax:/dev/scanner, a umax ASTRA 1200S<br>
flatbed scanner), xscanimage is usually immediately aborted with<br>
the error message "wire_read: unexpected EOF". When I am<br>
persistent and repeat selecting the menu entry, after about 20-30<br>
attempts xscanimage will usually start. When called via the<br>
"device dialog" menu entry, the success rate seems to be slightly<br>
higher.<br>
<p>
Versions of the involved components:<br>
Kernel: Linux 2.1.42, libc: 5.4.38, <br>
gimp: 0.99.13, sane: 0.65, gtk+: 970925<br>
SCSI interface: Asus SC-200, ncr53c8xx driver<br>
<p>
When called as a standalone program, xscanimage normally works<br>
(except for occasional crashes on startup - about every 2nd call<br>
will fail). When the device is given on the command line<br>
("xscanimage umax:/dev/scanner") the following warnings are<br>
displayed.<br>
<p>
** WARNING **: file gtkwidget.c: line 2813 (gtk_real_widget_queue_draw): "GTK_IS_WIDGET (widget)"<br>
<p>
** WARNING **: file gtkwidget.c: line 2813 (gtk_real_widget_queue_draw): "GTK_IS_WIDGET (widget)"<br>
<p>
I don't know enough about sane, gtk and gimp to make any sense of<br>
this. Below is the output when xscanimage is called as a gimp<br>
plug-in with all debug variables activated. It doesn't look<br>
particularly helpful, but maybe somebody can detect anything<br>
unusual in it:<br>
