I restarted Firefox, so that the .local/share/zathura directory did not exist yet (as it is local to the sandbox), and I couldn't reproduce the problem at this point. I tried again several times after removing the .local/share/zathura directory.
The real bug may be that bookmarks.sqlite became "corrupt" (?) in some sense. The fact that the problem is reproducible with such a corrupt bookmarks.sqlite file may be a consequence of this bug, but I don't know the zathura internals. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
