simple-scan doesn't use selected scanner from settings

[Dan Berindei]

I have two wireless all-in-one printers, one of them is in the local network and another is in another, unavailable, network. The available printer is set as the default.

Every time I start simple-scan, it tries to use the unavailable scanner. I can go into preferences and select the other scanner, and I can see with dconf-editor that the preference is indeed saved. However, when I re-start simple-scan, it switches to the unavailable scanner (the setting stays the same in dconf-editor, until I open the preferences dialog).

I have tried disabling the unavailable printer, but that doesn't make any difference - simple-scan still selects automatically it on startup.

I'm using simple-scan 3.4.1 on Fedora 17.

I have tried starting simple-scan with debugging enabled but I didn't get anything in the log.

thanks for your bug report. could you attach an excerpt of what is stored in the config?
also could you attach a log created with:

2. Include the debug output of simple scan by running it from the command line: simple-scan --debug > simple-scan.log 2>&1

thanks!

1. I dumped the config after setting the correct scanner in the preferences (Photosmart B110):

[dan@localhost] dconf dump /org/gnome/simple-scan/
[/]
document-type='text'
page-dpi=150
page-height=1753
page-side='both'
page-width=1275
paper-height=0
paper-width=0
photo-dpi=300
save-directory='/home/dan/Downloads'
scan-direction='top-to-bottom'
selected-device='hpaio:/net/Photosmart_B110_series?zc=HPCBxxxx'
text-dpi=150
window-height=400
window-is-maximized=true
window-width=600

2. After that I ran `simple-scan --debug > simple-scan.log 2>&1` and clicked the 'Scan' button. After a while I got an error in the GUI and I dumped the config again - it looked exactly the same.

3. I then closed the application and dumped the config again - this time the 'selected-device' line changed to the unavailable scanner (Photosmart 5520):
selected-device='hpaio:/net/Photosmart_5520_series?zc=HPxxxxxAxxxxxx'

4. I checked the log and it only contained this line:

** (simple-scan:1937): WARNING **: scanner.vala:801: Unable to get open device: Error during device I/O

Note: I mangled the printer ids.

This is still an issue using Simple Scan 3.12.1 in Ubuntu 14.04. We have 4 printer/scanners attached to our network. Choosing any scanner in the Preferences window (other than the first one) sets the selected-device field in settings. When you exit and restart Simple Scan and return to Preferences, the Scan Source dropdown will initially be empty (about 1 second), than will populate with the network scanners set to the first one. If you start Simple Scan and scan without opening Preferences first, it will scan from the first in the list, but does not change the stored settings. Here is my settings output:
$ dconf dump /org/gnome/simple-scan/
[/]
text-dpi=150
window-height=400
page-width=595
window-is-maximized=false
paper-width=0
window-width=600
paper-height=0
selected-device='hpaio:/net/Officejet_6700?zc=HP6C3BE59599A3'
page-dpi=72
photo-dpi=300
page-side='both'
document-type='text'
scan-direction='top-to-bottom'
page-height=842

My users would love to see this fixed, since there is no easy way to distinguish in the drop-down which one is theirs when we have more than one of the same model. They just have to memorize their position, and update their memory if the list changes.

Attached is the debug output from opening Simple Scan with the above settings and doing "All Pages From Feeder" without going to Preferences.
