This also applies to openSUSE 13.1 RC-1. Problem version of Thunderbird is 24.0.1 which is in 'update' repo for 13.1 and 'mozilla' for 12.3. I've reverted to the version of Thunderbird (24.0) on the 64-bit installation DVD and Lightning works OK again so I've locked this version.
The calendar that I'm using is local; I use no external calendars such as Google.
