I had the same issue (folders with no name which couldn't be removed) on
Evolution 2.28.3 on Lucid Lynx.
Backed up my .evolution folder then deleted
.evolution/mail/mapi/myaccount folder and restarted Evolution. Took a
couple of minutes to rebuild inbox and other folders from exchange but
problem
I don't have msfonts or windowsfonts installed and I am getting firefox
crashes. Running from the terminal I would get this after the crash:
firefox
QSettings::sync: filename is null/empty
Segmentation fault (core dumped)
I have run with strace and attached the result.
