[pypy-issue] [issue1154] IndexError in jitviewer

[kostia.lopuhin]

New submission from kostia.lopuhin <kostia.lopuhin at gmail.com>:

I get an exception when trying to load jitviewer webpage:

127.0.0.1 - - [28/May/2012 20:56:02] "GET / HTTP/1.1" 500 -
Traceback (most recent call last):

__init__
    self.parse_code_data(op.args[2][1:-1]
IndexError: list index out of range

I get the same error both on log.pypylog, supplied with jitviewer, and on log from my 
application. If I change op.args[2] to op.args[1] everything seems to work fine (op.args is a 
two element list).

Steps to reproduce:

1) Install 1.8 build locally (tried a nighly build, got same results)
2) hg clone pypy repository
3) add it to PYTHONPATH
4) make a virtualenv with pypy from step 1, activate it
5) hg clone jitviewer repo
6) run python setup.py develop in jitviewer dir
7) run jitviewer log.pypylog
8) Go to localhost:5000
9) Observe traceback

Using Ubuntu 12.04 64 bit.

I understand this is highly unlikely that this is a bug in pypy or jitviewer, just wired...
