Sync libaqbanking 5.0.10-2 (universe) from Debian unstable (main)

What actually was the build failure?

debian/check-required-gwen-version.sh
WARNING:
A built binary package has a dependency on libgwenhywfar which requires a
higher version than required in build dependencies. This is a hint that the
build dependency might need a higher version of libgwenhywfar-dev too, which is
probably fulfilled at the moment and thus didn't cause a build failure on THIS
system, but may cause a build failure on OTHER systems.
make: *** [binary] Error 1
dpkg-buildpackage: error: /usr/bin/fakeroot debian/rules binary gave error exit status 2

Because version in Build Dep was 4.0.3, and it was build with 4.1.0 :)

This bug was fixed in the package libaqbanking - 5.0.10-1ubuntu1

---------------
libaqbanking (5.0.10-1ubuntu1) oneiric; urgency=low

  * Update Build-Depend libgwenhywfar60-dev to 4.1.0 to fix FTBFS. (LP: #799225)

Weird. Why didn't it cause build failures on Debian?
https://buildd.debian.org/status/fetch.php?pkg=libaqbanking&arch=amd64&ver=5.0.10-1&stamp=1308086510

The patch in libaqbanking 5.0.10-1ubuntu1 is insufficient because it causes incomplete symbols files. Hence I would like to request a re-sync with Debian unstable, which has this bug fixed in libaqbanking 5.0.10-2 plus updated symbols files.

sync request ACKed...

Micha: On Ubuntu it only failed on i386, but can't find build logs for that in Debian.

And a small remark:
The version error it gives is 'WARNING:', but it makes build fail (as it has an exit 1).
Shouldn't this be replaced by ERROR? Cause a Warning shouldn't be a build stopper imo.

Jean-Louis: regarding WARNING vs. ERROR you're partly right. In case the build stops this seems to be rather an error than a warning. However, the check is some guesswork which is intended to *warn* me in cases where the check fails on first build. In this particular case the check didn't fire for my Debian build. I assume the reason why the check didn't fire is that the new symbols in libaqbanking that picked up the newer Gwenhywfar version were generated by a Gwenhywfar macro. In the sense of the Debian Policy this means that the newer version in the build-dep is not required, i.e. the check including its warning message was wrong! Without this check the package builds without errors and with the older Gwenhywfar version installed.

Anyways, this check helps me (in some cases) to upload a package with insufficient build dependencies.
