Hi Guys:

Let me tell you that I work with monodevelop with great satisfaction as 
my primary IDE for about 2 years now and currently in my robotic 
framework project monoBOTICS (http://www.monobotics.ic.uach.cl/) witch 
use lot of devices, etc and allways very solid and stable (Fedora 8 
monodevelop 1.0)...

Currently I moving to Fedora 10 and I have installed monodevelop 2.0 
alpha 1 (waiting for the alpha 2 rpms to test the integrated debugger) , 
but I get a very unstable behaviour and lots of hung up of monodevelop 
doing many diferent things, even simple one some time, so there is no 
easy way to tell you how to reproduce the errors, but in most of the 
cases the error messages are about "_wapi_handle_unref " things (bellow 
full error messages and stack traces..)...Also I get a very weird 
keyboard behaviour, like when I pres "." the autocompletatios start and 
I get the list of properties/functions of the object, but then when I 
press the down arrow cursor key to move down on the selection list, the 
cursor move to the subwindow bellow (output error subwindow usually...) 
and simillar behaviour when I press up arrow in codecompletation...

Any ideas about how to do to fix those things?, I need to wait for next 
rpms?, compile monodevelop from sources (hopefully no)?

Errors:

#MonoDevelop allways start with a:
WARNING: Cannot find Mozilla directory containing libgtkembedmoz.so. 
Some Addins may not be able to function. Please set MOZILLA_FIVE_HOME to 
your Mozilla directory.
WARNING [2009-03-05 16:09:17Z]: Inotify watch limit is too low (8192).

See http://www.monodevelop.com/Inotify_Watches_Limit for more info.
FATAL ERROR [2009-03-05 16:09:17Z]: A platform service implementation 
has not been found.

Don't know if is really critical, but after that it load and work...then 
when it crash the usual message is:
