[Evolution] Crash on folder rename

[Kenneth Porter <shiva well com>]

I have a folder named "Spam" which receives all probable spam messages.
As it's the primary target of all my manual moves, I figured I'd rename
it to "_Spam" to get it to sort to the top, but this didn't work. Today
I opened Evo (1.0.1) and decided to rename the folder back again. I had
the folder selected (the Folders pane is permanently displayed),
right-clicked and selected Rename, then changed the name and hit return.
I saw the name change in the Folder pane, but then the message list and
preview pane disappeared and the dreaded "email component has exited
unexpectedly" message appeared. The last interesting thing in the debug
log is "GdkWindow 0x2600acf unexpectedly destroyed".

BTW, before each POP3 session starts, I see "camel_exception_get_id
called with NULL parameter." Probably unrelated, but might be of
interest.
