Operating System: Linux 3.13.0-30-generic x86_64

-- Information about the crash:
I have open same folder in which I extracted images from video file with ffmpeg. It is true, there were lots of images (more than 35000), but very small (about 22KB).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
