Bug 251831

Application: kmail (2.0.89)
KDE Platform Version: 4.5.68 (4.6 >= 20100912) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I had the inbox of one of my accounts selected.  I right-clicked it, and selected "Update Folder", and it crashed.

ASSERT: "collection.isValid()" in file /home/kde-devel/src/KDE/kdepimlibs/akonadi/standardactionmanager.cpp, line 454

It also happens on other folders in other accounts (including Local Folders).

I've had similar crashes when selecting "Add to Favourites".  The other options in the context menu (that bring up dialogs, for example) don't seem to cause crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
