           Summary: Pages with javascript crash konqueror embedded
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: tahoward at nc.rr.com


Application that crashed: mythbrowser
Version of the application: v0.32
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-127.fc12.i686.PAE i686
Distribution: "Fedora release 12 (Constantine)"

What I was doing when the application crashed:
I'm using MythBrowser from the latest MythTV .21.  On Fedora 9, everything
works.  On Fedora 11 and 12, I get this error immediately after visiting any
page with Javascript, such as http://www.slashdot.org.  I've seen this error on
a Pentium 4, a Pentium M, and a Core 2 Duo.  Except for the part about
happening on ARM, the symtoms reported here:
http://old.nabble.com/Crash-on-arm-td14735115.html seem to match, and the given
fix to ustring.cpp also seems to fix the problem.
