Comment 15 for bug 1619616

There was a hack put into Mir around the end of June 2015 as linked by Daniel (https://code.launchpad.net/~vanvugt/mir/fix-1391976/+merge/262678). As the comment suggests this was pending "a proper fix will come from libprotobuf itself but this way we don't need to wait for that".

This "hack" was removed at the end of July 2015. I don't see a corresponding change to protobuf. So I suspect I have been chasing the wrong fix. I found some differences that look related and tried patching them locally. I still have to figure out why patching things seems to work locally - especially with the typo in the patch file. Clearly I'm doing something wrong. :(
