           Summary: loading SVG graphic and going back crashes Konqueror
           Product: konqueror
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konq-bugs kde org
        ReportedBy: vlukas gmx de


Version:            (using KDE KDE 3.3.1)
Installed from:    SuSE RPMs
Compiler:          gcc 3.3.4 The compiler used to build the KDE and Qt packages is \
                that of Suse, not mine.
OS:                Linux

If a SVG graphic is opened in Konqueror and the browsers back button is clicked \
quickly, i.e. before the graphic is fully loaded, Konqueror crashes due to an \
Segmentation Violation. The crashing behavior does not depend on the concrete SVG \
file. As an example given, the crash can be reproduced by following this link: \
http://www.home.unix-ag.org/simon/penguin/penguin.svg Just click "Back" in Konqueror \
a (very) short time after the URL is entered. I can not reproduce this behavior with \
other file types than SVG graphics.

The following is a backtrace delivered by Dr.Konqi:
