Hello everyone,

These days I have been testing Db Browser for sqlite :-)
Windows 7 (64 bit) with yesterday's daily build (3.10.99).

Today, I have tried to import a huge txt file downloaded from here (332 mb):
http://download.geonames.org/export/dump/allCountries.zip

When you unzip this file you get the AllCountries.txt file , which is around 1,4 gb !!!
It contains 19 columns (UTF-8 encoding; tabs as separator; no header as first column).
You get more information about this table, named "geoname", here (bottom of the page):
http://download.geonames.org/export/dump/

To make it short, Db browser for Sqlite always stops working when It reaches around 11% for this importing.
Worst of all, when you click "cancell" to kill the process the software always crashes.
To make matters even worse, when I try to reopen my database it is no longer available !
It looks like it has been changed in "read-only" mode.

Here is my Dropbox video recorded to show this crash (Windows 7 - 64 bit):

To always reproduce this crash on Windows 7 (64 bit) you need to:

• Create a new database (e.g. Prova.db) ;
• Click on File > Import from CSV file ;
• Select the AllCountries.txt file (19 columns - fields are selected) ;
• Click on Ok to start the process ;
• The importing usually stops when it reaches 10-11% ;
• When you click on "Cancell" BrowserSqlite 3.10.99 always crashes ;
• When you try to Open again your Database (Prova.db) it is readonly .
