           Summary: Reproducible crash when clicking on non-existing
                    directory in the left pane.
           Product: k3b
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: trueg@k3b.org
        ReportedBy: magnusj@it.uu.se
                CC: michalm@jabster.pl


Application that crashed: k3b
Version of the application: 1.68.0
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.30-gentoo-r6 i686

What I was doing when the application crashed:
When starting k3b I'm greeted by the message "The file or folder
/home/bakterie/work/gepi/Papers that cite API does not exist.". This is
correct, it doesn't exist. I've no idea why k3b tries to look in it. This
non-existing directory is shown in the left pane, and if I click it k3b
crashes.
