Application: konqueror (4.14.9)
KDE Platform Version: 4.14.11
Qt Version: 4.8.6
Operating System: Linux 4.2.3-200.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:1) i was only doing normal web browsing when it crashed. 2) previously, I was working with xml code and unsuccessfully  adding binary code in the xml document. I launched the xml code through Dolphin which in turn launched konqueror as a viewer which notified me about xml code errors. 3) I am developing code which instantiates storage on the heap using Code Blocks and GCC. Often, i exit the debugger without heap clean up. Probably I caused this problem.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
