[imp] pear Net_DNS 1.0.6 gives WSOD upon login

[Brent]

Tried to upgrade the Net_DNS pear module from 1.0.5 to 1.0.6.  Doing  
so results in a completely blank page returned after login (firefox,  
ie, and chrome)...also referred to as the White Screen Of Death.   
Reverting Net_DNS to 1.0.5 resolves the issue.

No idea where to look for debugging.  Just tried the latest build of  
horde/imp/dimp that was released today and it has the same behaviour  
with Net_DNS 1.0.6.
