Never record error

[luca.ingianni@…]

Basic situation:
It seems my database got corrupted (still not sure how or why). I've tried using mythweb's database cleaning tools to clean up the corruption, but it seems it didn't work, or at least not entirely. Some specific planned recordings are not recorded. In one case, at least an entry in the recorded programs list is created (but apparently not even a single byte of recording data written), in the other, not even that. This channel can be watched live without problems, and until a few days ago, these very recording definitions worked.

Specific situation:
I tried to to further clean up the database: I noticed there was a planned recording in my listing that seemingly didn't have a channel attached to it, so I tried to delete it in mythweb (button "never record"). The reaction to my input was this backtrace.

I've attached a screenshot of the planned recordings with what clearly seem to be broken database entries.

Since all defective planned recordings seem not to be deleteable, I will now plunge into the database and remove the offending rows.

Expectations:
1) The database should not become corrupted at all (gee, who'd have thought :) ), and especially not seemingly without cause
2) Recordings (particularly corrupted ones) should always be deletable
3) the database checker should discover (and ideally also fix) the broken rows
