    <p>I play a movie with MPMoviePlayerController. Later, the app is "restarted" (meaning a pseudo-reset, where all viewControllers are removed and the user returns to the home screen), and the same movie is played again.</p> <p>This leads to a crash in iOS 3.2.2 on the iPad:</p> <blockquote> <p>[AVPlaybackItem fpItem]: message sent to deallocated instance</p> </blockquote> <p>I have no idea where that comes from. Seems to be something private. Has anyone experienced and possibly solved the same problem?</p> <p>The stack trace for that particular address:</p> <pre><code>(gdb) info malloc 0x11471400 Alloc: Block address: 0x11471400 length: 76 Stack - pthread: 0xa0630500 number of frames: 34 0: 0x9534e0c3 in malloc_zone_calloc 1: 0x9534e01a in calloc 2: 0x343edc9 in _internal_class_createInstanceFromZone 3: 0x344b5c9 in _class_createInstanceFromZone 4: 0x344b5ef in class_createInstance 5: 0x3326b57 in +[NSObject allocWithZone:] 6: 0x332583a in +[NSObject alloc] 7: 0x536ab67 in -[AVPlaybackQueue queueItemWasAddedNotification:] 8: 0x27f586 in _nsnote_callback 9: 0x328d165 in _CFXNotificationPostNotification 10: 0x2762ca in -[NSNotificationCenter postNotificationName:object:userInfo:] 11: 0x5354982 in -[AVQueue itemWasAdded:atIndex:] 12: 0x5354801 in -[AVQueue insertItem:atIndex:error:] 13: 0x53549d8 in -[AVQueue appendItem:error:] 14: 0x535c3be in -[AVController addNextFeederItemToQueue] 15: 0x535b06f in -[AVController checkQueueSpace] 16: 0x5359f46 in -[AVController setQueue:] 17: 0x535ac62 in -[AVController setQueueFeeder:withIndex:] 18: 0x30eee20 in -[MPAVController reloadFeederWithStartIndex:] 19: 0x30deed7 in -[MPMoviePlayerControllerNew _prepareToPlayWithStartIndex:] 20: 0x30dc686 in -[MPMoviePlayerControllerNew prepareToPlay] 21: 0x27f586 in _nsnote_callback 22: 0x328d165 in _CFXNotificationPostNotification 23: 0x2762ca in -[NSNotificationCenter postNotificationName:object:userInfo:] 24: 0x281238 in -[NSNotificationCenter postNotificationName:object:] 25: 0x31596d1 in -[MPMovie _determineMediaType] 26: 0x291b87 in __NSFireDelayedPerform 27: 0x32747dc in CFRunLoopRunSpecific 28: 0x32738a8 in CFRunLoopRunInMode 29: 0x3aaf89d in GSEventRunModal 30: 0x3aaf962 in GSEventRun 31: 0x52b372 in UIApplicationMain 32: 0x27be in main at /blablabla 33: 0x2735 in start </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
