/tmp/zim-myuserid Directory == Slow Startup

[martyg]

On startup, zim checks for a directory /tmp/zim-myuserid.
If this directory was left behind from a previous run, startup is delayed significantly (15 seconds) before the main window is shown to the user.

If I close zim manually (Ctrl-Q) this directory is automatically erased. No issue.

If zim is terminated due to the X server closing, this directory is left behind even after all zim processes have terminated.
The next zim invocation will be delayed as described above.

It would seem reasonable to expect zim to delete this directory in both cases.

This issue observed in Arch Linux, using i3wm.
