This is almost certainly a duplicate of a comment in Bug 39771 

The bug tracking software did not add my details and just kept coming back to viewing possible duplicates despite me aknowledging this as a duplicate so I'm adding it as a new bug so that the backtrace etc. are available for debugging

The crash can be reproduced every time.

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