Steps to reproduce:
1. Open print dialog on any page in chrome.
2. Click on CUPS printer to select
3. Segfault

Segfaults as soon as the CUPS printer is clicked on in the printer selection dialog; i.e. not when the "Print" button on the dialog is actually clicked.

Additional Info:
- CUPS version 1.4.4
- The printer being used is a printer on the network.
- Choosing the option to "Print to File" works fine; additionally, cups is working fine in my configuration. If I print to PDF, then use lpr to print to the same device, there is no problem. Additionally, I am able to access the CUPS configuration web interface in chromium no problem.

Can you please attach your PPD files in /etc/cups/ppd/ and if you are using a printer on a remote CUPS server also the PPD files from /etc/cups/ppd/ there?

Hello,

I have reported the same bug for Debian here:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=606685

I you are interested, in can provide a core file.
My problem has been fixed with an upgrade to cups 1.4.4-7 (Debian squeeze).

Cheers
Damien
