PROOF-Lite crashes at the finish of the application

Hi Gerri,

There's a new issue with PROOF-Lite in v5-34-08. (Not sure when it began, we only noticed it here, and it still affects v5-34-00-patches.)

At the end of an application the TProofLite destructor tends to crash. In an SFrame job the bracktrace looks like this:

#8 0x00002abf45aa6460 in TCollection::Contains (this=0x0, obj=0x1ae14e80)

It seems that some list pointer doesn't get initialized in TProofLite.

On lxplus this can be re-created with:

svn co svn://svn.code.sf.net/p/sframe/code/SFrame/trunk SFrame
cd SFrame/
source setup.sh
make
cd user/config
sframe_main FirstCycle_config.xml

Cheers,
Attila
