Source: clutter-gtk Version: 1.8.0-2 Severity: important (Not sure if this counts as RC-critical or not, given it's not really an FTBFS)
Since clutter-gtk 1.8.0-2 added git_disable-dubbel-buffer.patch it bumped up gtk_req_version to 3.21.0, but the build dependency for libgtk-3-dev is still only (>= 3.19.4). This causes it to FTBFS on architectures which don't yet have gtk+3.0 3.21.0 built (either due to slow buildds or failed builds), such as sparc64. Regards, James
