I made another update, V0.16-4.

I finally managed to reproduce the failed size estimation followed by a black screen, as reported by TBP + get a log out of it.

Looks like it being caused by two separate issues - database becoming inaccessible and failed loading of status tiles.

I hardened the code running both, so it now will either work as intended or at least should not get the application to an unusable state and should print an error message.

I have also noticed during testing, that MyDocs sometimes becomes read only (for all applications). Did anybody notice something like this before ?

I don't know if this is caused by modRana or some other program accessing MyDocs. It can be fixed by connecting and disconnecting in mas-storage mode or by restarting the device. An appropriate mount/umount command would IMO also fix it.
