After I let all the startup messages settle down, as usual, I went into 
mythweb and attempted to delete one recording. the results:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 1191237984 (LWP 7538)]
0x0000000000000000 in ?? ()

So I tried touching the missing /mnt/mythtv/12282_20070118113500.mpg.png. I 
restarted mythbackend and tried again. Same segfault.

So I tried manually deleting both files. I reran mythbackend. Same segfault.

Do you think the issue might be with:
	adding: beryl as a remote file transfer

This is a master server and everything is local.
