Mail that causes akonadi to hang

Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

KDE-Version is 4.7.4 (the drop-down-list did not offer this version).

I have two mails (BTW both google calander invitations) which when either one of them gets displayed cause akonadi to hang somehow (no CPU-load).

Reproducible: Always

Steps to Reproduce:
1. Navigate to the folder containing these messages.
2. Click on either of them in the message list.
3. See how the message-contents are displayed.
4. Click on any other message.

Actual Results:  
From now on I can't view the contents of any message. The message-content-part only shows "Retrieving Folder Contents Please wait...".


Expected Results:  
Show the contents of the newly selected message.

When I restart akonadi using akonadictl displaying of contents is working again, until I click on one of those two evil messages.

While succesfully displaying a message also causes the console to print at least

  void Nepomuk::Query::QueryServiceClient::close()

(sometimes more) nothing gets printed after I triggered the bug.

I moved the messages to another folder. Had no influence on the bug.
