No luck my side yet but still desperately trying to find a solution. Will let you know if I find one.

In the mean time I have to manually monitor and remove incorrect galleries from articles.

 

Does anyone know where you can inspect the actual names of the uploaded zip folders. I know they get stored in numbered folders inside /media however is it possible that the actual zip files name (if it contains spaces or other characters) could be causing the problem?

Have just hit this problem too in K2 svn 2.5 . Am working on solution this morning

I cant recreate this now in SVN version :(

However I can confirm that we were using 2.4.1 and that the database had the same youtube tags on many articles in the  video column. If you can I suggest removing from db and testing with SVN version.

 

The save  function happens in the item model and there is nothing really in there that looks wrong or obvious as a culprit. It uses main core Joomla functions to perform the save Alan Sparkes said:

Thanks for taking a look. I'm going to check out my db again however I am always cautious as this problem is on one of my larger more active site so I need to be careful not to break something.

OK I think I may have solved teh puzzle here .... Apparently you will have to manually tell the item ( article) in K2 to show the gallery - item view options - Image gallery - show! And it worked for me... I hope it does for you too :)
