Code review comment for lp:~ballogy/bamf-qt/fix-imports-dir-location

I don't know how to truncate the path, but it's really required to be relative? I think that it's a Qt plugin, and therefore it should be installed into the same place where Qt installed. E.g. appmenu-qt uses the similar QT_PLUGINS_DIR variable, which is also an absolute patch and cannot be prefixed:
