Why do Mono applications only start from their own directory?

If I want to run the application monodevelop, I need to chdir to /usr/lib/monodevelop/Bin and then execute ./MonoDevelop.exe. This is the same for all other Mono applications such as banshee, tomboy, etc. If I attempt to run the Mono applications from another location by simply running monodevelop, or even from their own directory, I get _TypeInitializationExceptions_ like this: > behrooz@behrooz:/usr/lib/monodevelop/bin$ monodevelop > FATAL ERROR [2012-05-04 11:24:39Z]: MonoDevelop failed to start. Some > of the assemblies required to run MonoDevelop (for example gtk-sharp, > gnome-sharp or gtkhtml-sharp) may not be properly installed in the > GAC.

I have tried reinstalling all Mono, Wine, GTK, Glib, X, Gnome packages.

apt-get --purge --reinstall install $(dpkg --get-selections | grep mono | grep install | grep  -v deinstall | awk'{print $1}')

I also tried strace on "open" and got nothing by myself. System Configuration: - Debian 6.0-updates 64 bit - Kernel 3.2.0-2, 3.2.0-1, 3.1 and 3 EDIT: not a kernel thing - Gnome 3.4 EDIT:but a gnome thing - Mono 2.10.5

update: with upgrading to the new MonoDevelop 3.0.2 and latest Mono, I can run MonoDevelop with command monodevelop in terminal, no chdir. but gnome-shell cannot run it. Finally found it: as root: cd /usr/local/ find | grep mono|xargs rm -rf # Use with caution/some applications may get messed up (stellarium has MONOchrome images...)
