Will look into it.
BTW - I think we can use the "assign" feature if somebody is going to work on an issue - but PLEASE only assign yourself and not others ?

Hrm.. could you check that

1. The image is really missing and
2. If you do a tracker.php get avatars the image in question is downloaded?

If that's true, I think we should run get avatars at the end of every update action (from the hooks)

?

Finally got around to running that. We'll see what kinds of things are logged now.

Sorry I should have tested first... Seems there is (again) some issue with avatar downloading..
Since we have a debug mode (i forgot about that since it's undocumented :P) this brings up:

$ ./tracker.php get avatars -v --noprogress
...
+DEBUG Fetching avatar for user: aapis
+DEBUG Fetching avatar for user: aaronhudon
DEBUG Can not retrieve the avatar for user aaronhudon
+DEBUG Fetching avatar for user: aaronschmitz
+DEBUG Fetching avatar for user: Achal-Aggarwal

+DEBUG Fetching avatar for user: adrianrosian
+DEBUG Fetching avatar for user: advans
DEBUG Can not retrieve the avatar for user advans
+DEBUG Fetching avatar for user: aekboy2010
...

There are a lot with no apparent reason..
So I added (again) the lovely user-default.png: - I hope nobody gets offended by a smiley ?

That's happy smiley ;)

I like our happy default. Much friendlier than the Joomlacode or Facebook outlines ?

So let's hope we got this fixed for now..
