I am seeing the same thing with 0.139 on Mint 13 (mate), but the lockup seems
to be heat related.  Binary group has 108,000+ entries, upon click to enter the 
processor core temp rises 16 to 18 degrees F.  If downloads are in progress, 
are stopped and the screen info goes away. Closing the application (pan), 
waiting a
few seconds for the temp to drop and restarting pan continues the downloads, as 
nothing happened.

This is happening with an AMD Phenom II x 4 965 @3.4 Ghz with 8 gig of memory.
