Shotwell started to crash on my computer. I have realised it’s due to corrupted JPEG files in my picture directory. I have started to remove corrupted files by hand, based on entries from shotwell log.cache/shotwell/shotwell.log. However after removal of several files, I have noticed corrupted JPEG are spread all over my photos. Luckily, there is simple way of detecting corrupted jpeg files using Python Imaging Library (PIL).
- First, clear shotwell cache
- Install dependencies
- And run python
Note, this will remove all you libraries from shotwell!
rm -r ./.cache/shotwell ./.local/share/shotwell
sudo easy_install -U PIL Send2Trash
Below code will move all corrupted .jpg and .jpeg files to system trash.
import os, sys from PIL import Image from send2trash import send2trash def is_jpg(filename): try: i=Image.open(filename) return i.format =='JPEG' except IOError: return False cdir = "." if len(sys.argv)>1: cdir = sys.argv i=j=k=0 for root, dirs, fnames in os.walk(cdir): sys.stderr.write(" %s\n"% root) j += 1 dirs.sort() jpegs = filter(lambda fn: fn.lower().endswith((".jpg",".jpeg")), fnames) for fn in jpegs: fpath = os.path.join(root, fn) if not is_jpg(fpath): sys.stderr.write(" %s\n"%fn) send2trash(fpath) k += 1 i += len(jpegs) print "%s files scanned in %s dirs. %s files removed."%(i, j, k)
