This also makes the package FBTFS in sid, therefore I've raised the
severity of the (original) bug report.

Well, actually we have 2.0207+dfsg+really+2.0134-1 in Debian, i.e.
upstream 2.0134; d/changelog reads:


  [ Niko Tyni]
  * Temporarily revert to upstream version 2.0134 while changes
    in external DTD handling are revisited upstream. Thanks to
    Vincent Lefevre for the reports. (Closes: #1005281, #1003810)

Uploading 2.0210 would be desirable, but needs checking of those bugs
and other changes, and also involves some work as the structure of
the distribution has changed.

As a quick bandaid to fix the FTBFS bug and unblock libxml2, I've
prepared an upload with only the one upstream commit added as an
additional quilt patch (which makes the test suite pass on sid and
trixie, i.e. with libxml2 2.9.14 and 2.12.7); I'm now also cloning
the bug as a reminder that we need to invest the time to try and
update to a newer upstream version.
 

Cheers,
gregor
