Okay, so when you rebuild the Ubuntu package from source the bug is
not present and the largish diff suggests they have added patches on
top of vanilla 0.14.0.
If the Ubuntu source ships with a number of .diff/.patch files that
get applied during the build then you could manually bisect this.
That means rerunning the Ubuntu build but with only the first half of
the list of patches applied. If that has the bug then split the
untested patches in half too and continue the test cycle. If the bug
is not present then split the patches in half and continue testing
until you reach the point where the bug goes from present to fixed.
