mail app problem on JB: cannot attach

Hi. I have this weird problem: When I try to share something from any app via e-mail, where it should normally open the mail app with the thing attached, what happens is that the mail app quickly opens and closes, almost instantly. So I am unable to attach anything to my emails. No draft is created.

Iphone 5, IOS 6.1, jailbroken with evasion. I looked at what packages I installed might be causing the issue, I couldn't find anything that seems related.

I tried rebooting the device with volume up button pressed (and so had mobile substrate disabled), the problem persisted.

I appreciate any help.

 

I ended up purchasing the attachments+ tweak.
