[Evolution] Msg stuck in preview window

[Gerard Ceruti <glc ceruti co za>]

Hi
Evolution 3.2.3 and Ubuntu 12.04.

I have a message stuck in the preview window, there is a message on the
bottom line about retrieving a png file:

0-I have check that the png file is available
1-I have pushed the cancel button, just get a message ¨(cancelling)¨
2-I have tried Ctrl-M, same email still in the window
3-Moved the email account from imap to pop3- same result
4-rebooted - same result

What other actions can I try ?.

I am sure the original email does not exist on gmail any more.

Thanks
GC
