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)

If you could follow the instructions at https://wiki.gnome.org/Apps/Shotwell/ReportingABug, that would be a huge help.

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

PS Have submitted a bug report on Bugzilla, as suggested.

It wasn’t clear from the Bugzilla interface that both files would be submitted along with the report - I selected them individually, but only the second one’s name was visible when I hit the commit button.

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: (shotwell:3394): Gtk-WARNING **: GtkScrolledWindow 0x11707130 is mapped but visible child GtkScrollbar 0x8b54798 is not mapped (shotwell:3394): Gtk-WARNING **: GtkScrolledWindow 0x11707130 is mapped but visible child GtkScrollbar 0x8b54798 is not mapped (shotwell:3394): Gtk-WARNING **: GtkScrolledWindow 0x11707130 is mapped but visible child GtkScrollbar 0x8b54798 is not mapped (shotwell:3394): Gtk-WARNING **: GtkScrolledWindow 0x11707130 is mapped but visible child GtkScrollbar 0x8b54798 is not mapped ** ERROR:/build/buildd/shotwell-0.18.1/src/Photo.vala:3330:photo_get_pixbuf_with_options: assertion failed: (pixbuf != null) Aborted (core dumped) Any advice?

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%. Michael

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”).

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
