[Mono-osx] How to load custom font

[mrgutis]

I am using
/
string urlString = NSBundle.MainBundle.PathForResource("MyFont", "otf");
NSUrl url = new NSUrl(urlString);			
NSError error = CTFontManager.RegisterFontsForUrl(url,
CTFontManagerScope.Session);/
in AppDelegate's FinishedLaunching method (while tried in different places
with no effect on stopping crashes). Now I can see that font loaded
succesfully and I can use it but application becomes unstable - draggin
and/or resizing it crashes. While resizing tends to crash more often.
I am using Mac OS X 10.6.7, MonoDevelop 2.4.2, Mono 2.10.2
Here's what i get in console on crash:
