Description:
Wikimedia failed to generate the thumbnails of an PNG file I uploaded via the " UploadWizard" web interface.
The uploaded PNG file check ok on pngcheck so I guess it's a server side malfunction.

The link to the commons.wikimedia page is :
http://commons.wikimedia.org/wiki/File:Yamanaka-lake-panoramic.png

And the error message when trying to desplay a thumbnail is :
Error generating thumbnail

Error creating thumbnail: convert: magick/splay-tree.c:883: GetValueFromSplayTree: Assertion `splay_tree != (SplayTreeInfo *) ((void *)0)' failed.

Version: unspecified
Severity: normal

I can repro this on my x86_64 Ubuntu 11.04 box, with ImageMagick 6.6.2-6.

convert: magick/splay-tree.c:883: GetValueFromSplayTree: Assertion `splay_tree != (SplayTreeInfo *) ((void *)0)' failed.

Bug does not occur with ImageMagick 6.6.9 that I built a couple weeks ago as a test... Fix is in 6.6.7 and later.

Upstream bug: http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=18136

There's already a request in to update ImageMagick to 6.6.7 or later for bug 26233:

http://rt.wikimedia.org/Ticket/Display.html?id=1444

Duping since solution (upgrading) is the same.

This bug has been marked as a duplicate of bug 26233 ***
