Thank you for your bug report.

Hey Mardy, do you think you could have a look? That seems an issue in uoa patch we carry for shotwell

There is a better stacktrace on the errors.ubuntu.com report: https://errors.ubuntu.com/problem/e678dd3bb4c4325a55d018bb42eccadaf32a5633

Unfortunately the most important part (the code from shotwell) is missing debugging information. I'll try to investigate anyway; it looks like Online Accounts is returning an error, and the code which I wrote in shotwell doesn't handle it well.

Hi! I tried to reproduce this bug, but with no luck. Philip (and others who can reproduce this), can you please give me some more information about when this precisely happens? Is it consistently reproducible? Does it happen when you click on "Login", or before that?
If you can reproduce it reliably, can you please try reproducing it after settings the following environment variables:

export SHOTWELL_LOG=1
export G_MESSAGES_DEBUG=all

Then you'll find the logs in ~/.cache/shotwell/shotwell.log

Incidentally, I found an issue in libsignon-glib while reproducing this bug, but I don't think it's the cause of this:

Hi,
Strangely I can't reproduce it even by publishing the same photos (though using a different FB account). Unfortunately I can't remember precisely how this happened. My apologies.

I'll try again ASAP to see if I can reproduce this bug using other methods.

I just had a crash. Happened the instant I tried to publish to flickr. I upgraded to 14.10 yesterday and have had several crashes since, uploads seem to work about 50% of the time.

I ran with:

export SHOTWELL_LOG=1
export G_MESSAGES_DEBUG=all
shotwell &

attached shotwell.log but not all details seem to be there.

Forgot to post crash message.

shotwell:21178): Gtk-DEBUG: Connecting to session manager
*** Error in `shotwell': corrupted double-linked list: 0x000000000890d7d0 ***

The Flickr double-free crash is reported at bug #1382843 (and easily reproduced). I don't know that it's the same as the bug reported for this ticket, so I'm not marking as a duplicate.

Looking at #1382843 this is almost certainly what I am seeing rather than
this one.

the uoa support got removed in https://launchpad.net/ubuntu/+source/shotwell/0.26.1-0ubuntu1
