Can’t show group chat Skype in Ubuntu 14.04

I installed Skype in Ubuntu 14.04,  but when I logged in to Skype, I only show and chat with my friends and can’t show any groups, I fixed it by the way:

Open chat box with any my friend and type:

/dumpmsnp   #show details about your connection

And I showed log:

System: MSNP: Connection Data:
 * Status: LoggedOut

Ref:It’s LoggedOut   => It is problem

To solve it, type:

/msnp24

Then log out and restart Skype. After that, type again:

/dumpmsnp 

And I see:

System: MSNP: Connection Data (MSNP24):
 * Status: LoggedIn

And I also see all my groups in Skype, and the issue was solved.
