This may or may not be related or helpful so my apologies in advance if it's unhelpful, but has anyone here with trouble tried doing a OS X combo update and see if that fixed the problem?
More then a year ago I bought a refurbished 12-core MacPro where I moved all my stuff to from an older 6-core running X.9.5. Everything seemed smoothly till I noticed some things didn't work like preview crashed all the time, ScreenSnapz Pro wouldn't launch anymore and more things that where "off".
After doing everything I could think of to troubleshoot, from (re)moving RAM, Zapping PRAM to buying and running Disk Warrior I called in help. Long story short, I was told that my use of apps that clean up your Mac like Cocktail and MacCleaner also removed some files my computer needs which might be fixed if I did a clean install of X.9.5
In the end for me a combo update fixed the issues I was having.
Since the problems with creating Gif's is not something the majority of users experience, it might be that something Hype needs to create these gifs is no longer onboard your OS, which a combo update might fix.
I'm just wildly guessing here but it may be worth a shot?
