Jakub, is that the complete file? It's basically empty. If so, the solution to your problem is to download the linked file from comment #2, and use it to replace the file you have pasted here. You need to do the replacing as root user.
Reinstalling won't help, as it appears that the Ubuntu package is damaged. Can you post the output of $ apt-cache policy inkscape please? This will tell us where the package you are using stems from (I'd assume the official Ubuntu 16.10 repos, but who knows...). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638373 Title: End marker/start marker drop-down menus are empty To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/1638373/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
