           Summary: selecting File --> Print --> causes crash in konqueror
                    with ASSERT in qprintdialog_unix.cpp \"index >= 0\"
           Product: kdeprint
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW

          Priority: NOR
         Component: general
        AssignedTo: kde-print-devel at kde.org
        ReportedBy: zahl+kde at transbay.net


Version:           Version 4.1.81 (KDE 4.1.81 (KDE 4.2 >= 20081128)) (using
Devel)
OS:                Linux
Installed from:    Compiled sources

Non-reproducible :(

I tried twice to repeat this and couldn't.

I was on bugs.kde.org, picked "file" then "print", and konq crashed with this
backtrace (note the ASSERT in thread #1):

Application: Konqueror (konqueror), signal SIGABRT

I can't tell if this is a Qt bug or a KDE bug.
