Trying to use Special:Properties creates the following error. There is no predefined property with "___gld".

I don't know what this ___gld thing is. It's not native SMW, nor is it in any of the extensions I have locally. Running any non-common or SMW+ semantic extensions?
## Analysis We had to deactivated the Semantic Glossary extension (which defines the special property ___gld) and during the update procedure (or call to Special:Properties) ___gld properties where still "active" and when SMW tried to de-solve the ___gld property it couldn't find any definition because SMWDIProperty failed. This could happen to any special property that is defined outside SMW core and comes/goes with an extension. This behaviour has be verified against SMW 1.7.0.2 / SMW 1.8 alpha.
[1] should solve this problem for inactive/former registered special properties. [1] https://gerrit.wikimedia.org/r/#/c/31829/
No, this problem had not been fixed in the above commit. It has been fixed only now in the following change (review pending): https://gerrit.wikimedia.org/r/#/c/32201/ Status can remain fixed though.
