414234 - initPrintSettingsFromPrinter fails with Postscript/default

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect)

Description

[Andrew Schultz]

With the new gnome print dialog, I'm getting assertions and exceptions when I open the print dialog.  I get:

###!!! ASSERTION: null data pointer: 'Not Reached', file /build/andrew/moz-debug/mozilla/xpcom/string/src/nsTSubstring.cpp, line 667
getPrintSettings: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIPrintSettingsService.initPrintSettingsFromPrinter]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://global/content/printUtils.js :: anonymous :: line 130"  data: no]
###!!! ASSERTION: null data pointer: 'Not Reached', file /build/andrew/moz-debug/mozilla/xpcom/string/src/nsTSubstring.cpp, line 667

nsPrintSettingsGTK.SetPrinterName is being called with "Postscript/Default" (it decides to use "" instead).  gtk_print_settings_get_printer returns NULL (==>ASSERTION) and then it calls gtk_print_settings_set_printer and passes an empty string.  When GetPrinterName is called, gtk_print_settings_get_printer still returns NULL and ends up using nullPrintName.  Then setPrinterDefaultsForSelectedPrinter calls InitPrintSettingsFromPrinter and passes the empty string, so it returns NS_ERROR_FAILURE (==> exception).

I don't have a real printer (I just print to files), so all I have is Postscript/Default.  Printing itself works fine.  I'm not sure what the expected behavior of the printer name is, but it should be doing this stuff without causing assertions and exceptions.

AFAIK outdated.
