Can't get repetierHost working on my system (no replies)

Hi,

Forgive me for my bad english. I have installed repetierHost 1.6.0 on my linux gentoo system few months ago.
All was working well till las month. I have done 2 major upgrades on my system and now I have this error:

Double id:L_SHOW_TRAVEL_MOVES
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: cHRM chunk does not match sRGB
System.Windows.Forms.SplitContainer doesn't implement interface System.ComponentModel.ISupportInitialize

Debug info from gdb:

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

I have tried to reinstall libpng and mono, tried to remove 1.6 version of libpng to keep just one but the problem persists:
