> If a new queue is created through QMF but never used, the store creates a queue directory
and places an uninitialized journal file into it. If qpid-qls-analyze is used to look at this
store, it fails with and error message:
> {noformat}
> Traceback (most recent call last):
>   File "/usr/bin/qpid-qls-analyze", line 109, in <module>
>     M.run()
>   File "/usr/bin/qpid-qls-analyze", line 97, in run
>     self.jrnl_recovery_mgr.run()
>   File "/usr/bin/qlslibs/anal.py", line 73, in run
>     jrnl.recover(self.high_rid_counter)
>   File "/usr/bin/qlslibs/anal.py", line 358, in recover
>     self._check_alignment()
>   File "/usr/bin/qlslibs/anal.py", line 423, in _check_alignment
>     remaining_sblks = self.last_record_offset % qlslibs.utils.DEFAULT_SBLK_SIZE
> TypeError: unsupported operand type(s) for %: 'NoneType' and 'int'
> {noformat}
> Thanks to Jitka Kocnova for finding this bug. Method to reproduce:
> Using a clean store:
> {{qpid-config add queue q --durable}}
> then stop the broker and analyze:
> {{qpid-qls-analyze --stats <store-path>}}
