[Bug 1774136] Re: apport mistakenly duplicates bugs with similar but not identical python stacktraces

[Brian Murray]

Looking at a couple of crash reports from different releases in the
bucket we can see the DuplicateSignature is the same.

https://errors.ubuntu.com/oops/0df57774-6459-11e8-b827-fa163ed44aae

DuplicateSignature
/usr/bin/update-manager:AttributeError:<lambda>:resize_to_standard_width

DuplicateSignature
/usr/bin/update-manager:AttributeError:<lambda>:resize_to_standard_width
