Segfault during multiple deletes

[Robert Kulagowski]

I had just queued up a big delete of all the programs in one particular group using the "/" from Watch Recordings, then executed the delete. While that was going on I started watching another program, saw that it was a repeat, exited back to watch recordings then queued that one for deletion using "d". I then started watching another program, and that one hung on the frontend during playback after a few seconds. Eventually got the "lost connection to backend" popup.

Backend had:

Program received signal SIGSEGV, Segmentation fault.

Really looks like a Qt bug, not mythtv.

[tim@…]

This happens to me as well. Any time I delete a couple of recordings in a row, mythbackend segfaults.

[Isaac Richards]

Hey, guess what. Still works for me. Unless you have new information, don't reopen the bug.

[Robert Kulagowski <bob@…>]

It doesn't work for me.

[Robert Kulagowski <bob@…>]

Just kidding. :)
