OK.

Very helpful!

It did in my case though: see below for the full details.

OK, I tried all that again. SPOILER: apparently still nothing after
issuing the mysql commands, but what eventually fixed it was deleting
.ICEauthority. Long story follows:

Pasting the code in the terminal didn't work: it kept on waiting for
input even after the EOF and, if I gave it a ^D after that, it
complained about that too. So I connected to the database manually and
pasted the commands at the mysql prompt. This worked.

After that I launched mythfrontend. This didn't work.

ICE default IO error handler doing an exit(), pid = 12220, errno = 32

Then I deleted .ICEauthority.

Then I relaunched mythfrontend. This time it worked: I could get a GUI
from mythfrontend and, from it, it did ask me if it was ok to upgrade
the database from one version to another; I said yes and shortly
afterwards I had a working system again! Yay!

2011-05-07 07:49:42.807 Deleting UPnP client...
Error in my_thread_global_end(): 1 threads didn't exit

So in summary the mysql cure was fine, but the other error about
.ICEauthority was preventing mythfrontend from showing me its gui and
therefore completing the conversion (note BTW that, without the gui,
after a while it would exit by itself, even if I didn't press
anything). Your suggestion of deleting that file allowed the
mythfrontend to continue and thus fix things.

I no longer get the warning about the missing themeinfo.xml file, but
the frontend works fine. I guess it's because I must be using another
theme. I wonder why it was complaining about it before and not now,
because themeinfo.xml is still missing in those particular
directories.

I see a bunch of other errors in the log, including many instances of
"Application asked to unregister timer 0x0 which is not registered in
this thread. Fix application." that I can't understand, as well as a
bunch of "PlaybackBoxHelper Error: CHECK_AVAILABILITY 'xxxx.mpg' file
not found", which must be what happens when you get a failed recording
and then you have a listing in the directory but no file to watch. But
at least now the frontend starts up and I can control the box and
watch movies, so broadly speaking it's fixed!

Thanks a lot!
