Result:
"Error generating thumbnail
Error creating thumbnail: Image was not scaled, is the requested width bigger than the source?"
Expected result:
15px thumbnail of the 16×16 image.
That image worked before, but the thumb itself had probably been created a long time ago.
Version: unspecified

says the solution for Wikimedia sites is to remove the following 2 lines from CommonSettings.php
// Disable server-side GIF scaling
$wgMediaHandlers['image/gif'] = 'BitmapHandler_ClientOnly';
CommonSettings.php is linked from here:
http://noc.wikimedia.org/conf
See:
http://noc.wikimedia.org/conf/highlight.php?file=CommonSettings.php
See also the long discussion thread about animated GIF resizing linked in the table of contents here in the Common Graphics village pump:
http://commons.wikimedia.org/wiki/Commons:Graphics_village_pump#toc
The Commons thread says that system administrators can edit CommonSettings.php to remove the 2 lines. See:
http://meta.wikimedia.org/wiki/System_administrators#List
Can someone please contact some system administrators? I don't use IRC. Andrew Garrett provided the fix for the animated GIF scaling problem according to
https://bugzilla.wikimedia.org/show_bug.cgi?id=16451
Can he remove the 2 lines from CommonSettings.php? He is listed as a system administrator on the Wikimedia list. Can any system administrator remove the 2 lines from CommonSettings.php? Please do so.
Wikia GIF scaling is working. Does this mean it will also work on Wikimedia sites?
I searched Wikia.com for animated GIFs:
*http://www.google.com/search?q=site%3Awikia.com+animated+gif
Here are some results of that search:
*http://halo.wikia.com/wiki/Category:Animated_Gifs
*http://tinierme.wikia.com/wiki/Action_items
Compare the thumbnail and full-size versions of the images. GIF scaling is working. For example:
*http://halo.wikia.com/wiki/File:1217685012_Reallyhighskyjack.gif - 1.55 megabytes.
*[http://images4.wikia.nocookie.net/halo/images/thumb/b/b5/1217685012_Reallyhighskyjack.gif/120px-1217685012_Reallyhighskyjack.gif thumbnail of same image] at 175 kilobytes.

I tried this on testwiki and it didn't work: http://test.wikipedia.org/wiki/File:Neue_Gedichte_%28Heine_1852%29_A_003.gif
Apparently it's breaking somewhere but I don't know where.

Never mind, I'm an idiot, it does work. Enabled on all wikis now.
Repurposing bug back to original report per Tim.
With trying link to thumbinail image directly, message:
"Error generating thumbnail
Error creating thumbnail: Unable to save thumbnail to destination"
See also http://commons.wikimedia.org/wiki/Category:Saint_Alexander_Nevsky_Church_(Peterhof) - many files without thumbinail! (all uploaded 2011-09-14, 19:17)
Please fix this annoying problem.

Is that even related to this bug? Sounds more like bug 39697.
Cannot reproduce either with given examples. Closing report as WORKSFORME but please reopen (and provide a specific example) if this problem happens again.
