We can see how the crash signature is created by apport for python
tracebacks here: http://bazaar.launchpad.net/~ubuntu-core-
dev/ubuntu/quantal/apport/ubuntu/view/head:/apport/report.py#L1206.
The problematic bit follows:
return self['ExecutablePath'] + ':' + trace[-1].split(':')[0] + sig
Here were just using the first part of the last line of the trace to
create the signature. Considering just the trace[-1].split(':')[0]
portion we have the same partial signature for bugs 772083 781360 -
'SystemError'. However, if we expand this out a bit we have:
772083: SystemError: E:Encountered a section with no Package: header,
E:Problem with MergeList
/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_natty_partner_binary-i386_Packages,
E:The package lists or status file could not be parsed or opened.
781630: SystemError: E:Write error - write (28: No space left on device), E:IO
Error saving source cache, E:The package lists or status file could not be
parsed or opened.
which is quite different. For the partial signature we could use all of
trace[-1] or a portion there of. I have code that will download all the
tracebacks for a package and compare their old partial signatures to a new one.
