Sorry but I don't know. I happened to see the problem, and the problem was reproduced by very simple operation I stated in comment #0.
This is still happening in TB12.

What should happen in this case? Just catch the exception and do nothing? Or show some prompt?
I can do the clean exiting from the function. But if we want any UI stuff...
What about a status bar message? Is there something already available? There must be other cases where we want to tell "No folder selected" so I could reuse that?
I'd suggest if no folder is selected, fall back to the default account root, and show the dialog.
Good idea. Patch coming.

Since the UI isn't really changing, I don't think you need a ui-review from me.

So I'll give it a regular review instead.  ;)

The code looks pretty good.  The change is small and simple.  r=me.

Well, very similar problem happens when using Folders->Favorite, when there are none to show, the left tree pane is empty. Restarting TB comes up with the msgAccountCentral.js pane showing about every action available, because it does not know which account is selected (none is). Clicking most of the commands throws an exception like
Error: window.parent.MsgJunkMail is not a function
Source File: chrome://messenger/content/msgAccountCentral.js
Line: 292

Is this filed somewhere?
Actually, that one bug is expected, that Junk feature is not ready, but was unintentionally exposed in the situation I described.
The real errors are
"Error: GetSelectedMsgFolder() is null"
