I've got mine working again now. Since the problem seems rare I focused on what makes my evolution data different: the size of my inbox/trash folders:
~$ du -sh .local/share/evolution/mail/local/Inbox* 1.6G .local/share/evolution/mail/local/Inbox 4.0K .local/share/evolution/mail/local/Inbox.cmeta 12M .local/share/evolution/mail/local/Inbox.ibex.index 85M .local/share/evolution/mail/local/Inbox.ibex.index.data 4.0K .local/share/evolution/mail/local/Inbox.sbd I noticed when I remove these (after backing up the entire evolution folder) evolution starts up (with some corruption errors) and still has other folders I've created. I restored from backup and this time just removed index/metadata files (i.e., Inbox.* but not Inbox itself). Running evolution from command line I saw a lot of output, presumably regenerating the files I removed, and it worked! My inbox profile is now: ~$ du -sh .local/share/evolution/mail/local/Inbox* 1.6G .local/share/evolution/mail/local/Inbox 4.0K .local/share/evolution/mail/local/Inbox.cmeta 12M .local/share/evolution/mail/local/Inbox.ibex.index 84M .local/share/evolution/mail/local/Inbox.ibex.index.data The .index.data file got a little smaller, and the .sbd directory was never regenerated. I can only speculate which if either of these were the problem. It is also possible that the sheer size of my Inbox wasn't the direct cause but only made it more probable for a certain kind of bug to affect at least one index entry for that folder. So if re- indexing Inbox and/or your largest folder doesn't resolve the problem it may be worth trying all the folders. Here's a condensed version of how I resolved the problem: ~$ cp -af .local/share/evolution evo.bkp ~$ rm -rf .local/share/evolution/mail/local/Inbox.* ~$ evolution -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774392 Title: After installing 11.04 Evolution wont start -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
