           Summary: Konqueror crash on back button clock
           Product: konqueror
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konq-bugs@kde.org
        ReportedBy: dfavro@gmail.com


Application that crashed: konqueror
Version of the application: 4.3.2 (KDE 4.3.2)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Clicked back, then back again in relatively rapid succession.  Page wasn't
anything special (no java or ajax; minimal flash) and presented no problems
with loading initially

I've had a few crashes navigating back and forth.

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".
