What steps will reproduce the problem?
1. delete a database from outside of qgis
2. open qspatialite, you get the errors shown below and qspatialite does not 
load
3. workaround is to remove the database from qgis db manager

This error happens if you have stored your DB on a temporary disk (usb key, 
....).

I'll try to fix this in the next version

in qspatialite!
