Window state of dialogs not correctly remembered between boots

[vanadium]

Zim 0.62 on Ubuntu 14.10

The state of dialogs such as TaskListDialog or InsertDateDialog is not correctly remembered accross reboots.

Steps to reproduce the problem

- Insert date
- Select another date format, turn calendar on

Next time in a current session, the settings are correctly remembered. However, after a reboot, ZIM reverts to a default state.

Could this be a problem with the cache (~/.cache/zim/notebook-home_vanadium_Documents_Zim_zim_Notes/state.conf) not being copied over to the actual notebook settings (~/Documents/Zim/.zim/state.conf)? I notice that at the start of the session, the section [InsertDateDialog] is lacking from state.conf in the cache. When I change the DateDialog, such section is written out in the cache once the notebook is closed. Settings are remembered on subsequent opening of the notebook, but are lost after the system rebooted. Apparently the changes written in the cache do not make it to the state.conf of the notebook.

(I guess this is a functionality introduced to allow opening a Zim notebook over a network, allwoing to keep track of changes on the local file system. My notebook however is just on the local drive)
