I tried to use %session in a hidden field and I got the following error message everytime I viewed the form:
Recoverable fatal error: Object of class stdClass could not be converted to string in webform\webform.module on line 2079.

I think I managed to track the error down to a $node-object which I accidentially stored in $_SESSION somewhere else in my application, and the error is caused by a str_replace call in webform.module; I guess a simple if (!is_object(...)) at the right place would solve the problem, but I'm not sure if that's the best way... ?

The token replacement would also fail if it ran into an array unexpectedly. For the time being I've just caste the replacement to a string to ensure it'll be replaced properly.

If $value is not a string, $replace and $find mess up, as they won't contain the same number of elements.
The patch below inserts an empty string replacement string in order to keep the 2 arrays in line.

This was corrected in the 2.7 version, which uses an entirely different replacement mechanism. Please reopen if the problem continues to exist.
