Crash on empty log message

[jaroslavas]

If I print empty log message

DDLogVerbose(@"%@", responseObject); // responseObject = @""

Bugfender sdk crashes:

I see you're using the DDLogVerbose macro, which is not defined in Bugfender. Are you using CocoaLumberjack?

I'm trying this test and it works for me:

- (void)testEmptyLogString
{
    id responseObject = @"";
    BFLog(@"%@", responseObject);
}

Are you sure responseObject is @"" and not nil?

[jaroslavas]

Yep, I'm using CocoaLumberjack. And BugFender is set up to just catch all logs: [Bugfender enableAllWithToken:@"my_token"];

[jgimenez]

I see. Must be something related to how CocoaLumberjack treats empty strings. Will look into it.

Version 0.3.16 should fix this. Please let us know if it's not working for you. Thanks for reporting.
