The scrolledwindow/scrollbar warnings may be a red herring; sometimes these kinds of warnings appear with different themes/custom GTK modifications (i.e. global menu). I don't recall anyone else reporting them.
The Directory Subimage / top pointer / IFD warnings are from Exiv2 and are nothing to worry about.
The "unable to fetch preview" warnings indicate what you think they indicate, your thumbnails are being generated on-demand.
The get_pixbuf_with_options assertion is, obviously, an issue. The source of the issue appears to be:
gdk_pixbuf_scale_simple: assertion 'GDK_IS_PIXBUF (src)
Thanks, Jim.
I’ve installed the necessary tools, and am running Shotwell through the debugger now.
By a process of trial and error, I’ve found that repeatedly running Shotwell on a cold-booted computer will eventually allow it to get through whatever it is that causes it to crash, and allow it to run normally (albeit with a number of warning messages, depending on what I’m doing).
That’s the state of affairs at the moment - apparently normal running!
I’ll give the procedure another go tomorrow morning (it’s nearly 1 am here), when I expect the crashes will have started again (if the last few days are anything to go by), and report on my findings.
Regards,
Michael

I’ve recently upgraded to Ubuntu 14.04, and installed Shotwell 0.18.1.
After a short spell of “Updating library” there is a period during which I can use Shotwell, but after a total of about a minute, the display greys out, and the program shuts down.
If I run Shotwell from the command line I get this:

Any advice? Suggestions as to further investigation?

…which might help to explain the problem.
Looking at memory use - when Shotwell is first run, about 12% of the available RAM is taken up, and this doesn’t go back down after the crash.
Subsequent runs of Shotwell seem not to affect RAM usage, which remains around 12%.

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.
Michael
