Unable to open / merge some old files with proxy inside (A5)

As in the title, if I try to open and old file with old proxy inside, 3ds max freeze and RAM raises quickly the maximum amount of RAM.
Also if I try to merge it (but not with every old proxy). If I create a new empty Corona proxy and load from disk the .cbin file, everything is ok!
In attachment the files.
With A4 and A5 ( 2013-05-30) no problem.
As Ondra suggest me, there is some bug in the asset tracking.

Proxy.rar (6.16 MB)

Up!

If I try to open some files with proxy created with old version, 3ds max+V5 crash. And, if I try to open some files with proxy created with V5, 3ds max + Old version crash. Very annoying… =(

UP! Can you help me? )

don’t worry, I’ll go through ALL bug reports. I am just still heavily jetlagged to do anything :frowning:
