            Bug ID: 321608
           Summary: Konqueror crashed while loading pages in the
                    background
    Classification: Unclassified
           Product: konqueror
           Version: 4.10.4
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konq-bugs@kde.org
          Reporter: contact@pierreroudier.net

Application: konqueror (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.6-200.fc18.x86_64 x86_64
Distribution: "Fedora release 18 (Spherical Cow)"

-- Information about the crash:
Konqueror crashed while it was the background, not being the currently active
window.
So no input from me (mouse, keyboard, ...). 

I had like 6 or 7 tabs opened at the moment. I think some of them were still
loading.
One tab was browsing deluge-web. The others were wikipedia pages.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
