Android Compatibility Library CursorLoader : java.lang.IllegalStateException: Cursor is closed -
i'm using cursorloader inside fragment android compatibility library. every time, on droid 2 (i'm unable reproduce on nexus 1 or sensation), seems cursors being closed soon, causing various errors. unfortunately traces don't point anywhere helpful in code (since issue why cursor being closed, not when android notices), i'm struggling figure out going wrong. has else encountered problem? (or have ideas might happening).
some stack traces:

i have no cue problem is, maybe helps pinning down.
create loggedcursor , setup cursor factory query gives loggedcursor:
class loggedcursor extends sqlitecursor { @override public void close() { log.d(tag, "cursor closed by:", new runtimeexception("stack trace")); super.close(); } } the runtimeexception created log stack trace easily, not throwing it. when cursor closed you'll see trace in logs.
hopefully, helps figuring out when , whom closed.
