Bug#486941: cannot apply changes

[Armin Fuerst]

Package: system-config-printer
Version: 0.7.81-4

When I try to apply changes, some values are not really
changes (for example "Orientation" in "Job Options"). In
console, I get following message:

Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line
1225, in on_btnApply_clicked
    err = self.apply()
  File "/usr/share/system-config-printer/system-config-printer.py", line
1234, in apply
    return self.save_printer(self.printer)
  File "/usr/share/system-config-printer/system-config-printer.py", line
1362, in save_printer
    printer.setJobSheets(job_sheet_start, job_sheet_end)
  File "/usr/share/system-config-printer/cupshelpers.py", line 202, in
setJobSheets
    self.connection.setPrinterJobSheets(self.name, start, end)
