Hello, I'm the user who had written that mistaken patch on Dolphin emu's page.
I am sorry for any possible trouble it caused. It was meant to fix a problem I have in Dolphin, where it segfaults randomly. It didn't work for me, but I found it on a forum, and thought I should include it in the page to see if other users benefit or not. Please see this Fedora forum post (not posted by me) for the original source. I think there might be a connection to these bug reports:  .
Hi, sorry I took so long to reply.
I don't think it caused much (or any) trouble, this was just to be on the safe side, in order to avoid some confusion for end-users (and also prevent them from using outdated versions). No big deal, I'm just happy it was fixed.
On another note, I'm not sure the dolphin-qt warning on top of the page is relevant: the idea of moving from WX to Qt dates from 2011, and even if the guy working on it has not given up yet, I'm guessing it won't happen before a long time after the next version is released. When that happens, updating the page should be natural.
