gdb python print truncated string

[Wesley]

Hi all,
  I have a question regarding gdb python.
I use gdb7.7 and python2.7.6.

Here is snippet that py-print one variable:
(gdb) py-print self
local 'self' = <Connection(timer1220182856=<_Timeout at remote 0x7f860614b220>, timer513645288=<_Timeout at remote 0xb42f760>, timer1248840930=<_Timeout at remote 0x7f85f7f4c300>, timer1678666863=<_Timeout at remote 0x7f85fec0ddf0>, timer888598936=<_Timeout at remote 0x7f860579a300>, timer1566174556=<_Timeout at remote 0xe69a7d0>, timer1307561941=<_Timeout at remote 0x7f85e41145a0>, timer1010094072=<_Timeout at remote 0xb42af40>, to_device={u'sendno': u'1252682169', u'msg_content': {u'message': {u'command': True}}, u'msg_type': u'2'}, timer2050775853=<_Timeout at remote 0x7f8606ddcb50>, timer1115907467=<_Timeout at remote 0x9c02140>, timer333587031=<_Timeout at remote 0xbb25450>, timer71350378=<_Timeout at remote 0x7f85e5e38220>, timer1044716881=<_Timeout at remote 0x7f86053094c0>, timer2069059536=<_Timeout at remote 0x7f85f3d3b530>, timer2139990080=<_Timeout at remote 0x8bd5370>, timer1121163931=<_Timeout at remote 0x99e5370>, queue=<Queue(unfinished_tasks=0, queue=<collections.deque at remote 0x7081600>, maxsize=0, all_ta...(truncated)

self is instance of Connection class.
So, actually, I wanna check self.status...but you can see the print is truncated.
I tried py-print self.status but failed.
After a lot google work, somebody mention gdb 'set print elements 0/-1', but still failed..

So, how to check self.status value?

Thanks.
