Bug#685202: debdiff:interdiff related failure when debdiffing Debian sqlite3 3.4.1-1 and Maemo sqlite3 3.4.1-1osso3

[Paul Wise]

Package: devscripts
Version: 2.10.69
Severity: normal
File: /usr/bin/debdiff
User: devscripts at packages.debian.org
Usertags: debdiff

The Debian derivatives census scripts found a case where debdiff's
interaction with interdiff causes debdiff to fail. This is with an old
version of the sqlite3 source package from Maemo 4.1.2. Below are the
commands you can use to reproduce the issue. This issue occurs with both
Debian squeeze and wheezy, the package data below is for wheezy.

pabs at chianamo ~ $ mkdir -p debdiff-sqlite-bug/{debian,maemo}
pabs at chianamo ~ $ cd debdiff-sqlite-bug/debian/
pabs at chianamo ~/debdiff-sqlite-bug/debian $ dget --quiet --download-only http://snapshot.debian.org/archive/debian/20070808T000000Z/pool/main/s/sqlite3/sqlite3_3.4.1-1.dsc
sqlite3_3.4.1-1.dsc:

pabs at chianamo ~/debdiff-sqlite-bug $ debdiff debian/sqlite3_3.4.1-1.dsc maemo/sqlite3_3.4.1-1osso3.dsc 
interdiff: hunk-splitting is required in this case, but is not yet implemented
interdiff: use the -U option to work around this
debdiff: error: interdiff -z /home/pabs/debdiff-sqlite-bug/debian/sqlite3_3.4.1-1.diff.gz /home/pabs/debdiff-sqlite-bug/maemo/sqlite3_3.4.1-1osso3.diff.gz gave error exit status 1
