Bool in session is turned into string

[eluser]Unknown[/eluser]
I have also enabled db stored sessions and i was standing in front of the same problem like the thread author.

I checked the session Library and it's the str_replace of the backspace.

My quick&dirty;solution was adding a if statment with preg_match and only replace backspace if needed.

Replace in the method _serialize

Code:

$data[$key] = str_replace('\\', '{{slash}}', $val);

with

Code:

if (preg_match('/\\\\/', $val)) {
    $data[$key] = str_replace('\\', '{{slash}}', $val);
} else {
    $data[$key] = $val;
}

I also added the opposite to the _unserialize method...

Hope it's useful for somebody and i hope the ci team fix this bug also in the next release.
I also posted on the open Bug Report the thread author opened.

btw great work guys for this framework! keep on rocking ^^
