Problem

Builds for all platforms fail with "broken" in the "Build Results" panel.

Below "Source Files" I now see

Sources could not be expanded: service error: RuntimeWarning)

Detailed error:

It appears that the problem was caused by a tag before-pkg-view on the source repo.

After deleting that tag, the source service runs flawlessly again, and package building starts.

Since there is this line

    <param name="versionformat">@PARENT_TAG@+git.%h</param>

in the _service file, it looks likely to me that it failed because together with that non-numeric tag it could not be interpreted as a proper version number; it would have been before-pkg-view+git.7c15db which of course is not a valid version number for RPM.

So complaining about this was probably correct, but the error message was very confusing. Please consider an error message that gives some hint to what exactly was wrong.
