Subject: Fix QTest::qExec crash with no command line arguments
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=afb0260f50f41fa72f8447fdb84f8d907a725fe5;p=profile%2Fivi%2Fqtbase.git

Fix QTest::qExec crash with no command line arguments

The documentation for QTest::qExec states that command line arguments
are optional and gives the following example:

 MyTestObject test1;
 QTest::qExec(&test1);

However, running this example leads to crash as argv[0] is accessed
without testing argc. This change fixes this bug.
