SemiModals stay in stack. Removing them from stack causes problems.

[steelzeh]

So after i show SemiModal and dissmiss it, and then i go ahead and popViewController it tries to pop to the semiModal which causes a black screen. Then i decided to remove the SemiModal viewcontroller from viewcontroller stack myself. But that causes a Unbalanced calls to begin/end appearance transitions

Is it only me that gets this problem? Should they on default be removed from stack/deallocated automatically? Or am i wrong?
