Description

When closing an issue via a commit message, the open issue counter shown on the repositories issue tab does not decrease.
The counter can be reset to the correct value by closing an issue from the web interface (but not by opening an issue).

I believe this worked correctly in 1.10, but I can not really say for sure.
