As I have chatted with other few users having some problems with mstatus , I realized that the problem is not app related. I just reflashed my device and installed mstatus-applet 0.4 and it work without problems.
As an example the guy which have lost his IM account access has discovered that the problem was something like pidgin-yahoo-support uninstalling it and everything return normal.
So from the point of view of the application itself, I mean code/develop, it is ok (I suppose).
So, the problem is that maybe mstatus goes in conflict with some other applications and it's hard to me to find out with which one.
Maybe it would be helpful for me that the guys who have problems with mstatus post (on pastebin) the dpkg -l output to see the complete list of installed applications.
I don't know other way to help out
