I don't understand some of the people commenting on the bug report. If they really want it fixed, then they should fix it. Making rude comments isn't going to make it go any faster.
As someone who had issues with a 4+ year old bug in FileZilla, can confirm. First time I developed anything serious in C++ and it took me only two evenings to develop a patch. Then some back and forth on the bugtracker, but it made it in soon after.
(For those interested, it's the ability to create a new, empty file on the server.)
I don't know how the trigger system is structured under the hood, but I could imagine it being somewhat comparative if you can properly call them. At least one of the commenters could have tried something or asked for pointers where to find it, that triggers others to actually work on it or at least help them work on it.
