Comment 4 for bug 58940

It did also happen at each login for me.
I get ride of it by removing all references to external calendars, I think I had something weird with my config. I tried once to add a google-calendar source but entered it in the bad section and then I was unable to delete it.
After some gconf cleanup the old not-really-existing-calendar is gone and the crash with it.

Sorry, I do not have any gdb backtrace, I just remember that this backtrace was harder to get than others as evolution ran another instance and did not use the one I attached. The crash at login time is probably triggered by the clock-applet.
When running evo itself, the mail part was working fine and everything went wrong when switching to he calendar part.
