I know you are getting tired by my rapid updates lately but I am really trying to pin down the crash during navigation. If you experience it with v0.0.9 and above, please install the new v0.0.9-30, raise the debug level (Now in General Settings) and post here or in a bug report the postmortem file. I have added some many debug logs to certain parts of the tile manager & the tile DB layer in which I hope will have one of these issues that causes those crashes.
