Also when you try to run the second instance of gthumb from the command line, you'll get this error:
GDBus.Error:org.freedesktop.DBus.Error.NotSupported: Application does not handle command line arguments This is fixed in gthumb 3.2.8. Get this version from Ubuntu 14.10 repositories. Don't forget to retrieve both gthumb and gthumb-data packages (due to the dependencies). Here's a bug report asking to update gthumb in Ubuntu 14.04 repositories to 3.2.8: https://bugs.launchpad.net/bugs/1323312 ** Project changed: linuxmint => gthumb (Ubuntu) ** Summary changed: - Mint 17 Mate 32-bit can only launch one instance of gthumb from caja file manager + Mint 17 - can only launch one instance of gthumb ** Changed in: gthumb (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327002 Title: Mint 17 - can only launch one instance of gthumb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gthumb/+bug/1327002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
