Title:
  Mono crashes while executing mono + Gtk# applications

Status in “mono” package in Ubuntu:
  New

Bug description:
  Platform: Intel x32 + Ubuntu Oneiric 11.10
  Package version: 2.10.5-1

  This error is still present in Ubuntu Oneiric for mono applications
  created with monodevelop and using Gtk#, but not, for some reason,
  applications bundled with the operating system.

  The same happened to me in Windows, and the problem disappeared
  upgrading to the current version of Mono (2.10.6). I guess this is
  going to be the same thing.

  Unfortunately, recompiling applications is not an option, as
  Monodevelop 2.6 is unable to find the Gtk# in the system (?). Again,
  the same happened to me in Windows, and upgrading to the current
  version of MonodeDevelop (2.8) solved the problem.

  Would it be possible to upgrade these packages to their current versions, so this bugs disappear?
  If not, how can I solve this in my system, so I'm able to use mono again?
