Subject: [PATCH 2/3] Fix possible crash when passing an invalid PAC URL
|
|
|
|
This commit checks whether CFURLCreateWithString() succeeded.
|
|
|
|
It does not appear to be possible to enter an empty URL directly in the
|
|
PAC configuration dialog but I can't rule out the possibility
|
|
that it could find its way into the settings via some other means.
