Public bug reported:
In raring we're using a new xorglog.py parser to extract info from the
Xorg.0.log file.
However, parsing of this file will fail if it includes invalid data
characters, and that failure will crash ubuntu-bug. It is uncommon for
there to be invalid characters in Xorg.0.log, but it can happen
sometimes via funky EDIDs for example.
The problem is not with the apport hook, but with python itself; this
can be reproduced independently of apport:
$ python
Python 2.7.3 (default, Jan 6 2013, 12:15:04)
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> buf = open('/var/log/Xorg.0.log', 'rb').read()
>>> len(buf)
26205
>>> ubuf = buf.decode('utf8')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 10154:
invalid start byte
>>> buf[10140:10180]
'tel(0): XX31G\x80B133XW1\n[ 27.376] (II)'
>>>
Also:
$ iconv -f UTF-8 /var/log/Xorg.0.log -o /dev/null
iconv: illegal input sequence at position 10154
The apport hook will need to catch this error, and bypass use of parsed
log data if this happens.
