[Bug 1353171] [NEW] Misparses dpkg status line, fails to write apport reports

[Anders Kaseorg]

Public bug reported:

For a while apt has not been writing apport reports for dpkg maintainer
script errors. Here’s why:

• pkgDPkgPM::ProcessDpkgStatusLine sees a line like
"status: cyrus-clients : error : subprocess installed post-installation script returned error exit status 1".
• StringSplit splits it into
list == {"status", "cyrus-clients ", "error ", "subprocess installed post-installation script returned error exit status 1"}.
• pkgname is set to Strip(list[1]) == "cyrus-clients".
• However, the original list[1] == "cyrus-clients " (with a trailing space) is passed to WriteApportReport.
• WriteApport fails to find "cyrus-clients " in the cache, and bails out.

Patch attached.
