            Bug ID: 340024
           Summary: Konqueror crashes when opening PDFs in new browser
                    tabs
           Product: konqueror
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konq-bugs@kde.org
          Reporter: Warp_7@gmx.de

Application: konqueror (4.14.0)
KDE Platform Version: 4.14.0
Qt Version: 4.8.5
Operating System: Linux 3.16.3-kern x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

I was reading http://bugs.ghostscript.com/show_bug.cgi?id=695259 and
middle-clicked on the attachment links in comments #6 and #7 to open them in
new tabs (using the Okular kpart). If I click on the two links in quick
succession, Konqueror immediately crashes upon clicking the second one. If I
give it some time inbetween or switch to the tab of the first link before
opening the second, Konqueror is usually fine.

Not sure if related:
If I go right to "Report problem" in the KDE crash handler, the error report is
completely empty. All it says is that Konqueror had a segfault. I have to
display the backtrace first before starting the error report assistant.

The crash can be reproduced every time.

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