Currently when I try to import the content to ar.wikiversity.org I keep hitting this error: 

Import is mislukt: A database error has occurred. Did you forget to run maintenance/update.php after upgrading? See: http://www.mediawiki.org/wiki/Manual:Upgrading#Run_the_update_script Query: INSERT INTO `globalimagelinks` (gil_wiki,gil_page,gil_page_namespace_id,gil_page_namespace,gil_page_title,gil_to) VALUES ('arwikiversity','1823','10','قالب','GFDL','Heckert_GNU_white.svg'),('arwikiversity','1823','10','قالب','GFDL','GFDL') Function: GlobalUsage::insertLinks Error: 1062 Duplicate entry 'Heckert_GNU_white.svg-arwikiversity-1823' for key 'PRIMARY' (10.0.6.41)

This is causing serieus problems for starting the project. 

I had this error also 2 times for xmf.wikipedia.org

The xml is here: http://evakrap.nl/wikimedia/

Since I cant upload it because its to big.

I don't understand the cause of this. The current procedure is this:
1. Fetch links already in globalimagelinks
2. Determine which links are not yet in there
3. Insert links not yet in globalimagelinks in the database.
Somehow between 1. and 3. an entry gets added to the database.

Doing INSERT IGNORE will probably solve the symptoms in both #1 and #2, but hide the actual issue. But I think that is not really bad for those kind of race conditions.

It's almost like we've got a stray caller that is pushing it doubley. Maybe.

Should be fixed in r92241.

Using action=purge&forcelinkupdate= gives sometimes:
