interface freeze after click on Clear #11

I am using aMule git from HEAD, compiled with wxOSX Cocoa v3.0.2 and Boost 1.58 (Debugging).
Every time I press the "Clear" button after a search the whole interface freezes.
From what I can see no related error shows up in the console.
I am pasting that (just for reference)...
