Marble is a virtual globe and world atlas — your Swiss army knife for maps. Find your way and explore the world!

In Marble's settings there is a button in the Synchronization tab to trigger a manual sync of owncloud bookmarks. Extend it such that when clicked once it is disabled and only enabled again when the synchronization is completed successfully, or after a timeout of 30 seconds.
