As soon as I select page setup or print in the file menu of either firefox or thunderbird, the application crashes. I use the latest firefox/thunderbird from the opensuse Mozilla repository. This crash also happens with openSUSE 11.1 using the latest 1.4.4 versions of cups. This crash does NOT happen with cups 1.3.x provided by the distribution and also did not happen with later 1.4 versions installed. It did appear after an update to 1.4.4-48 about a week ago. Reproducible: Always Steps to Reproduce: 1. Start firefox or thunderbird 2. Select page setup or print from file menu 3. Crash immediatly Actual Results: crash Expected Results: page setup or print dialog Here is a link to the mozilla crash report : http://crash-stats.mozilla.com/report/pending/3dbcc44a-3132-4547-a78f-e3f542... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Do you mean that the crash happens only for the one exact cups-1.4.4-48.1.i586 version from the Printing repository but does no longer happen if you install another cups-1.4.4-xxx.yyy.i586 version from whatever other repository? Which exact CUPS 1.4.4 version from which exact repository do you currently have installed on which openSUSE version and when exactly happens the crash for you? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Therefore I follow your updates of the Printing repo on a daily basis. I noticed the crash about a week ago, not sure which cups version from the Printing repo was the latests by then. The crash is still there with the currently installed cups-1.4.4-48.1.i586 from both http://download.opensuse.org/repositories/Printing/openSUSE_11.2 and http://download.opensuse.org/repositories/Printing/openSUSE_11.1 I had to install cups 1.3.x from the distro repos and zypper addlock cups to avoid it.
