Error sending long private message

[gmarcos87]

When I try to send a very long private message, the system gets mixed up. Looking at the log encounter this exception without handle:

It may be necessary to display an error message or calculate the total length before sending and locking the button until the user does not cut the message.

Another way is to send the fragmented message into multiple parts of the maximum possible size.

@gmarcos87 the error now appears as a dialog in the interface.

I'm going to close this issue in favour of continuing in #456
