Bug 292412

Version:           4.8 (using KDE 4.7.4) 
OS:                Linux

I just upgraded to KDE 4.8 via kubuntu packages and tried to start the formerly working kontact (which did crash), and then tried to start kmail stand-alone (which also crashed). The backtrace for the kmail crash is this:

Application: Kontact (kontact), signal: Segmentation fault
