MS SQL: sp_helptext failure causes crash in HeidiSQL

Sometimes I don't have access to all the objects in a database. In such cases I often experience HeidiSQL exceptions / crashes.

e.g. there is an object myschema.del_SomeProc in the one database. I don't have rights to this stored proc. When I'm writing a query and the autocomplete tries to retrieve info about the objects int he database, this is executed and it causes a crash:

EXEC sp_helptext 'myschema.del_SomeProc';
/* SQL Error (15197): There is no text for object 'myschema.del_SomeProc'. */

My suggestion is to consume and hide errors that are returned from sp_helptext.

This should be a simple fix?
