Hello.
So this is how I "fixed" it.
This really isn't a repair so much as a work around.
I'll just type the commands I used:
As root:
Code:
mkdir /opt/$USER.temp
mv -r /home/$USER/important_data /opt/$USER.temp
mv -r /home/$USER/.ssh /opt/$USER.temp
mv -r /home/$USER/.thunderbird /opt/$USER.temp
mv -r /home/$USER/.mozilla /opt/$USER.temp
Then, using the FC6 GUI I removed the user's account (including home directory).
Then I recreated the deleted account and transferred the data back from /opt/$USER.temp
When I logged in again, Tahoma was appearing correctly.
Don't know what the cause was but at least its been fixed.
