Have just installed 12.1 x86-64 KDE live cd and downloaded Evolution 3.2.1 from the repository.
Evolution updated data file to new format and appears to work fine for mail, contacts and tasks but Calendar crashes immediately on clicking the tab.
I have googled but found no specific reference to this issue.
Also, I have latest Evolution with Fedora 16 on a different system and it works fine.
Any suggestions?
