Summary: crash after password dialog on a local CUPS page
Product: konqueror
Version: unspecified
Platform: openSUSE RPMs
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: konq-bugs@kde.org
ReportedBy: kollix@aon.at
Application: konqueror (4.6.00 (4.6.0))
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.1
Operating System: Linux 2.6.34.7-0.7-desktop i686
Distribution: "openSUSE 11.3 (i586)"
-- Information about the crash:
- What I was doing when the application crashed:
I started konqueror http://localhost:631 to show the CUPS page.
I clicked on the "Admin" link and then on "Add printer".
I get a "enter user/password" dialog where I enter the root account
credentials.
After clicking on the OK button in that dialog, konqueror crashes.
I ran this inside valgrind and get the following:
