Bug#1117986: wsdd: Warning about a truthiness test, line 649

Package: wsdd
Version: 2:0.8-5
Severity: minor
Tags: newcomer

Dear Maintainer,

I'm on Debian trixie, but had other reason to allow testing packages
(pinned to not auto-install/upgrade).  Due to wsdd having been removed
for trixie release the system then picked up the testing version.

In this version I see this logged:

2025-10-13T10:17:11.990915+01:00 emilia gvfsd[398794]: /usr/bin/wsdd:649: DeprecationWarning: Testing an element's truth value will always return True in future versions.  Use specific 'len(elem)' or 'elem is not None' test instead.

which is from this section of code:

 646             elif dialect == WSDP_URI + '/Relationship':
 647                 host_xpath = 'wsdp:Relationship[@Type="{}/host"]/wsdp:Host'     .format(WSDP_URI)
 648                 host_sec = section.find(host_xpath, namespaces)
 649                 if (host_sec):
 650                     self.extract_host_props(host_sec)
 651             else:
 652                 logger.debug('unknown metadata dialect ({})'.format(dialect     ))

So, presumably `if (host_sec):` needs changing to `if host_sec is not
None:` or similar.  Actually, I'm wondering why there are () on the
current version, perhaps those just need stripping ?
  Obviously it currently works well enough, but will need correcting for
whatever future Python version changes the behaviour.
