Hi partha,

Let me address your first question,

You can easily solve this problem by going for a complete system update If you have an internet connection with good speed.Note that this process will address all the bugs in your current operating system.

You can do it by selecting ubuntu menu-->system->Administration->Update manager.

This will display a window of ubuntu`s update manager

Click the "CHECK" button and click "Install Updates".

I hope this will solve your problem.If you are not able to go for a complete update,Pls let me know and i will help you to update pidgin alone.But remember,Updating the whole OS is always recommended and takes little time.

Thanks benny, that solved my question.
