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".
