Trying to get XMG upgraded to latest version and getting this:

The only vague explanation I can give is that the following query failed to run during upgrade:

ALTER TABLE xengallery_media ADD COLUMN rating_weighted float DEFAULT '0' NOT NULL AFTER rating_avg
Run that query and for good measure re-run the upgrade with the XML file.

Running that returns this:

[SQL]ALTER TABLE xengallery_media ADD COLUMN rating_weighted float DEFAULT '0' NOT NULL AFTER rating_avg;
[Err] 1050 - Table 'yabucket/#sql-ib292' already exists

Well, that would probably explain why it didn't run in the first place. That error doesn't make any sense, though. The query is adding a column to a table. The error is stating that some other table already exists.

I can't see much info about it other than people describing similar effects after MySQL has crashed. There doesn't seem to be any concrete solutions in those cases, though. One solution seemed to be dropping the entire database, but that seems somewhat extreme :)

I should add, that the obvious solution is to try and drop the 'yabucket/#sql-ib292' table, but most people have said that doing that didn't work or that table could not be found (even though the error states it's available).

That's an error relating to a MySQL temporary table. I'd check your MySQL error log to see if it has any errors. This may be an indication of a disk space problem (where MySQL is creating temporary tables).
