Emulator

Your desktop environment is telling you that you have a bad color profile set.
Nothing to do with Dolphin from what I can see.

strange, but how on dolphin 3.5-1284 not appears this message?

You really should fix your desktop environment's Xorg color calibration if it's broken, regardless of whether Dolphin worked before or not. Gnome has color profile management things built-in, and KDE very likely has them too, so screw around with 'em until it starts working and your monitor looks a ton better. (I'll see if I run into this on my Arch Linux install, which runs Gnome 3 and has a proper color profile installed.)

This is due to a updated libpng complaining about one of our images somewhere. Being worked on.

thanx @Sonicadvance1...

I ended up running into this too, so, yeah, there goes my previous explanation. :P

Please, fix this error, i can't play ...

willianhotz1: Stop abusing our issue tracker for useless issue reports like this, please. Go to the forums instead in the future.

I'd close this issue as Invalid, but apparently Sonicadvance1 knows wtf is going on, so whatever.

FWIW the same error message appeared for me when I git pulled a month ago. Didn't happen before. I doubt the crash is related to this though (does not crash here).

However, I get a crash when starting wii games because of some bluetooth related code (even when using emulated wiimotes). You might want to try running a GC game and telling us if it crashes too (my guess would be "no").

Sorry for this. But @delroth, look
