Hmm, this one I cannot repro, could you attach the crash log (ELF) ?

The ELF also doesn't say much, added more debug messages to 1490.

Could you please attach standard debug log and ELF log from 1490, thx.

Assign back to me once you add the logs, thx.

Unfortunatelly again, from the logs isn't clear why the AV happened.

But I see some script events that could have a side impact on this, could you please try this with scripts disabled?

I'm trying on 1492 with scripts disabled and after defragmenting DB on HDD and can't reproduce, but I may have stumbled across a problem:

1) Open 1 Tab
2) Set it to iPod Touch Auto-Sync list tab (I selected Playlists in this tab)
3) Open new Tab
4) Switch to Entire Library then Now Playing
5) Go back to Tab 1 and it now shows the Summary tab (unexpected)
(log capturing this added to above link)

This could mean that between slow DB access and multiple changes Tab 2 by user and Tab 1 by itself it could get hung up on SQL transactions.

Even with scripts enabled on 1492 this isn't reproducible anymore. I would assume that defragging the DB may have been a factor in solving this.

Resolving, as it is no longer reproducable and seems to be just consequence of 0009380.
