<P>

I need some help debugging a problem (or ruling out that my
|
|
<BR>
|
|
backend is causing this problme):
|
|
<BR>
|
|
<P>When I run xscanimage with the latest CVS version of the Epson
|
|
<BR>
|
|
backend I get a segmentation fault when
|
|
<BR>
|
|
- Advanced options are _NOT_ selected
|
|
<BR>
|
|
- and I click on scan or preview
|
|
<BR>
|
|
<P>When the advanced options are displayed everything works fine.
|
|
<BR>
|
|
<P>The following output is produced when running xscanimage in gdb:
|
|
<BR>
|
|
<P>(gdb) run
|
|
<BR>
|
|
Starting program: /usr/bin/xscanimage
|
|
<BR>
|
|
<P>Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkGammaCurve'
|
|
<BR>
|
|
<P>Program received signal SIGSEGV, Segmentation fault.
|
|
<BR>
|
|
0x8054e37 in gsg_sync (dialog=0x8097ae0) at gtkglue.c:1334
|
|
<BR>
|
|
1334 curve = GTK_GAMMA_CURVE (dialog->element[i].widget)->curve;
|
|
<BR>
|
|
(gdb) quit
|
|
<BR>
|
|
<P>The fault happens in line 1334 of gtkglue.c.
|
|
<BR>
|
|
<P>Is this my fault, and if so, where should I look?
|
|
<BR>
|
|
<P>Thanks,
|
|
<BR>
|
|
<P>Karl Heinz
|
