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[1]
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)
