I thought Shotwell had mended itself yesterday, as it didn’t crash for many hours, and I was able to do a lot 
of tidying up and tagging jobs.

Full of confidence, I shut Shotwell down and rebooted Ubuntu - the crashes came back.

Starting up my iMac this morning, I had another go, and here’s what happened (I started it using the 
command-line “date >> crash.log;shotwell 2>>crash.log;date >> crash.log”).

My (apparently) successful run yesterday generated a large number of warnings like those above, and also...

L 8654 2014-09-06 15:02:36 [CRT] Directory SubImage1: Next pointer is out of bounds; ignored.

…

L 5689 2014-09-06 13:06:31 [CRT] Iop pointer references previously read Photo directory. Ignored.

L 5689 2014-09-06 13:06:31 [CRT] Directory Thumbnail: IFD exceeds data buffer, cannot read entry count.

…

Part of the tidying up process I went through yesterday involved the recreation of about 15000 thumbnails, 
which I dealt with by scrolling slowly through the whole library, following the generation of lots of 
messages like this:

L 3922 2014-09-05 18:35:53 [CRT] EventDirectoryItem.vala:109: Unable to fetch preview for Event [669/88896] 
Sun 7 Jan, 2001: Failed to open file 
'/home/michaelhendry/.cache/shotwell/thumbs/thumbs360/thumb0000000000006702.jpg': No such file or directory

(I had copied the database across from a previous installation of Ubuntu, but hadn’t copied the thumbnails).

I have a suspicion that the problem is with the photo.db database - is there a utility or a procedure which 
would allow me to check its integrity?

I have spent many tens of hours on my Shotwell library, and am prepared to spend many more if necessary, to 
continue to use it.
