[Evolution] Evolution 3.10.2 Can't empty (expunge) trash

[Linux <linux interworld net au>]

I use Evolution for more than 10 years on many SuSe and OpenSuse
PC's and Laptops.

I moved (new Install) from OpenSuse 12.2 Gnome with Evolution 3.6.4 to
OpenSuse 13.1 Gnome and Xfxe with Evolutions 3.10.2. 

Can't delete (expunge) files from the Trash folder stored on the IMAP
Server. Evolution 3.6.4 works OK.

The IMAP Server mail dir structure is:
/INBOX
/INBOX.Drafts
/INBOX.Send
/INBOX.Junk
/INBOX.Trash

Can't increase message text size with Ctrl + '+' shortcut. 
The Ctrl + '-' shortcut works fine. This is the same with Evo 3.6.4 and 3.10.2.
There was no problem with Evo versions prior to 3.6.4.

Have the same problems with Evolution 3.10.2 installed on Gentoo.

Thunderbird works fine.

Is there any fix?
