There seems to be maybe different Evolution crashes from UP4. There are 3 solutions I've come across. Two I've tried successfully, one I've read on the forum here.
The normal crash point seems to be when Evolution is receiving mail. So to fix, it might be necessary to quickly hit the disconnect icon bottom left of the window and rush to click do not synchronise before it crashes.
For me running evolution through strace once solved the crashing problem. I have no idea why.
strace -o out evolution
This didn't work on another computer but the issue there was junk mail filtering. If that was switched off, Evolution worked fine. Potentially the actual issue there was with bogofilter.
Edit -> Preferences -> Mail Preferences -> Junk
Further, another tack taken was to use Evolution's backup facility to do a backup and restore.
File -> Backup Evolution Data
Ensure the saved data is output properly. Then close Evolution and in a terminal type
rm -Rf ~/.local/share/evolution ~/.config/evolution ~/.evolution
Restart evolution and
File -> Restore Evolution Data
choosing the file you backed up to.
