Camera corrupts images

[Denny]

I am using a bq aquaris 4.5 ubuntu edition (14.10R20 Ubuntu Image Part: 20150312 Device Image Part: 20150310-3201c0a).

I wanted to take multiple photos.
After every shot the camera showed me a preview.
When I wanted to check my photos afterwards, checking the photo roll, I could find only 1 photo, while swiping to the next one it showed only a spinning "cycle of friends".

I checked the pics on Ubuntu Desktop and found corrupted files instead of image files (JPEG datastream contains no image).

Enclosed please find also the logfile from ~/.cache/upstart/application-click-com.ubuntu.camera.log

Status changed to 'Confirmed' because the bug affects multiple users.

Hi,
I have reported the same here: https://lists.launchpad.net/ubuntu-phone/msg12462.html but I got no reply.
Meanwhile I have updated to r22, but the problem remained.
With me it happens spontanously, But could it be connected to location services? At least two times I was not able to take a picture at a specific location, whereas some steps along everything went fine. So I went back to the first place and still was not able to take the picture.
It is really annoying. Last week I was on a hike in the mountains and every n-th picture is lost.
Now I usually check the images immediately.

I played around with this corrupted picture:
http://www.hjkl.at/trash/image20150423_080615249.jpg
and found out that it can be repaired.

first i installed the perl exiftool (sudo apt-get install libimage-exiftool-perl).
then I saved the exif analysis to an html file
exiftool -htmlDump image20150423_080615249.jpg >x.html
looking at the output I noticed a spurious End Of JPG Data Marker (0xFFd9) at Offset 0x11DAF.
Then I opened the image with ghex, overwrote that marker with zeros. Saved the File and now it's repaired.

Too bad that I have allready deleted so many of the corrupted files.

In the above report, the suggested context of failure is HDR creation. Is that the case here?

Yesterday some of my photos were corrupt as described here. I don't think it happened before.

There were End Of JPG markers like with @lumusan, but changing the FFD9 to 0000 unfortunately did not repair them.

This bug should be Critical.
