I’ve installed my Thunderbird files on a NAS which are shared by Samba. Thunderbird is not working fluent, and it often takes several minutes before a mouse click reacts.
It seems to me that this occurred after installing opensuse 12.1.
I’ve read about the samba-problems under opensuse 12.1, but I don’t have any corrupt files when writing to a samba share. Therefor, I have not yet replaced systemd-sysvinit.
