There has been one crash report with this (deobfuscated) backtrace, in version 1.40 on Android 3.2:

This seems to be happening somewhere in SyncAdapter.doRegularTasks(). It suggests a leaked Cursor, but I can't find any there that are not closed: https://github.com/murraycu/android-galaxyzoo/blob/master/app/src/main/java/com/murrayc/galaxyzoo/app/syncadapter/SyncAdapter.java
