LiteSpeed console crashes when configuring a Database restore. Exception: System.NullReference (4341567)

When selecting Restore details in the Restore wizard (eg. Backup Destination), the client console crashes and generates the following Exception and Stack Dump:

Exception: System.NullReferenceException
Message: Object reference not set to an instance of an object.
Stack Trace:

There are a few workarounds:
1.) script the restore using TSQLLitespeed stored procedures, eg. XP_RESTORE_DATABASE
2.) restore from the commandline using sqllitespeed.exe
3.) use LiteSpeed Extractor utility to obtain a native backup file from the LiteSpeed backu file.

For further information regarding LiteSpeed stored procedures and their related parameters, including commandline, refer to the LiteSpeed Help file (click Help in the LiteSpeed Console).

STATUS: Fixed in Version 6.0 of LiteSpeed
