When I enter a given folder that causes an Akonadi::ItemFetchJob to fail, the "spinning wheel" distraction that replaces the folder icon will spin forever. This happens in both Akonadi Console and in KMail.

The ItemFetchJob error was "Unable to fetch item from backend (collection 85, resource -1)", but I'd argue that it's irrelevant what the error was.

The point is that there was an error and, though the user may be unable to do anything to correct it, there should be a visible indication of that, including possibly information to be transmitted to the developers to aid in fixing that particular error. As it stands, the wheel spins forever, as if KMail or Akonadi Console were waiting for something to happen.

Reproducible: Sometimes

Steps to Reproduce:
1. Enter, for the first time, a folder that produces a fetch error
2. Note that the folder icon is replaced by the spinning wheel
Actual Results:  
The wheel remains spinning forever. No error message is shown, ever.

Expected Results:  
An error message should be displayed as soon as the fetch error was noticed.
