Comment 1 Javier G. 2013-06-03 14:47:12 UTC 
Still present this crash with the latest v4.10.2

Today I tried all the preview options (Control -> Configure Dolphin... -> General -> Previews), one by one, and I found that only when "Directory" and/or "Video files (MPlayerThumbs)" are checked Dolphin start crashing multiple times, as expected in this bug report.

In the case of the "Directory" option" I believe that this option crash only because a video is found inside a subfolder. Correct me if I'm wrong but this option preview images & probably other formats, so it's possible that it tries to check videos as well and when that happen then... crash! 

Finally, I verified what I said above: I tried enabling "Directory" preview and in subfolders with no videos this doesn't crash. If I disable the preview mode, put a video inside any subfolder and re-enable the preview mode it crash. If I disable again the preview mode and I remove the video file and re-enable the preview mode it doesn't crash.
Note: To be exact I used the Windows file manager for copying/deleting the video and Dolphin for enabling/disabling the preview mode.
