Spoiler
Only one or two people currently in the Thieves' Guild, Mercer being one of them, actually knows who Karliyah is and what she looks like. They also know her to be the murderer of their former guild leader. When you bring her to the guild home and show off the journal, all of them, all of them simply go "oh... okay well... yeah join our club!"
That's a very, very weak point of the plot because all of these people knew her to be a murderer, and all of these people are presented with a journal that has no factual evidence that it's not a fake... yet they all yell hooray and let her join the band.

Well... considering the one who told them that Kariyah was the one who killed Gallus was Mercer, who the journal says is stealing from the Guild and whom you could verify as a traitor given your own experiences with him (if they had bothered to give you a dialogue there), there is reason for them not to spring into action. Because it's a bizarre move on her part, you (who they probably thought had been killed) decide to walk right into their laps.
Consider this:
Why would Karliyah walk right into the HQ of a bunch of people who want her dead unless she had good reason to? They weren't able to find her for 25 years, why would she offer herself up unless she's telling the truth? What is there to gain?
Also, the journal can very easily be proven factual, and is done so in the questline. You know how? They open the vault. The journal says that Mercer's been stealing from the Guild's vault, and when they open it up it's been cleared out. Now, if someone came up to me with one of my best friends and said "The person who told you I killed our leader is lying. He did it. He betrayed our Guild and I have a journal to prove it," all the while a witness who is part of the group goes "That's right, he tried to kill me," and the vault is empty just like the journal said, it seems fair to think that these three independent sources are all telling the truth. After all, what's more likely? That the person who told you (without any corroborating witnesses to validate his testimony) who was good and who was bad is lying, or that Karliyah forged a journal, found someone to cover for her, and cleared out the vault in the Cistern without anyone noticing?
After they learn that Mercer's been lying to them and stealing from them, they obviously have no reason to trust anything he told them about the person who revealed to them that they were being conned, so why wouldn't they trust her? She didn't steal from them, and it's pretty obvious the person who told them she couldn't be trusted was lying.

...Yeah it's not intrigue worthy because we're not robbing the Hermaeus Mora blind!
